TomTom ONE

Note that the TomTom ONE is no longer in production and no longer available in most stores. It has been replaced by the TomTom ONE 3rd Edition and the TomTom ONE XL. The ONE 3rd Edition doesn’t have Itinerary Planning, but is compatible with the traffic receiver. Otherwise it is similar. The ONE XL is similar to the ONE but adds a widescreen.

(Watch a video of the tomTom ONE.)
The TomTom ONE, originally available only in Europe has finally made it across the pond to the USA, and we are very excited about that. On the surface, the TomTom ONE is a basic, entry level GPS navigation device. However once you dig down into the advanced routing features you really start to see where this GPS shines. We’ve taken the ONE through about one-thousand miles of testing, and here is what we think.


The TomTom ONE is what I could characterize as a slim and pocketable GPS. It comes with a standard 3.5 inch display which can show 64,000 colors. The display itself is quite nice; the colors do not shift much until you look at it from extremely wide viewing angles and it is plenty bright so that it will not wash out too much in direct sunlight. While the display does not automatically switch from day to night node, you can manually set night mode in three clicks. The night and day modes also have their own brightness controls so you can set it very bright during the day and very dark at night. There are also ten different color schemes to select from if you don’t like the default colors.

I was skeptical of the mount at first. It is a really simple design with only one moving part, the ball and socket joint. This joint type allows you to tilt or rotate the display to any angle while suctioned to your windshield. Typically, I prefer these ball and socket type connections since they are easier and faster to adjust. However the TomTom ONE mount was just a little bit too tight and a couple of times I pulled the suction off the windshield trying to adjust the angle of the display. Others have criticized the mount for being too short. The face of the ONE will be about 3-3.5 inches from the windshield. This worked just fine for me, and in comparison the Nuvi mount puts the Nuvi about 3.75 inches from the windshield so there is only about a .5 inch difference between them.

Along the top of the ONE is the power button, and a charger indicator light. Good move to put the charge light on top where it will not interfere with the display at night. The speaker is on the back and there is an SD card slot on the bottom. (The maps come loaded on the SD card.) Unfortunately, the USB/power connector is on the bottom of the device. This is one of the few faults I have with the TomTom ONE. Putting the power connector at the bottom limits how low on the dash the screen can be. To accommodate for the power connector I need to mount the GPS an inch or two higher than I would otherwise. Having the GPS rest on the dash in addition to being mounted via the suction cup also makes the GPS more sturdy, but unfortunately you can’t take advantage of that trick.

At 3.8 inches in width, one inch thick, and weighing about 5.6 ounces the TomTom ONE is highly portable. There is also functionality to create pedestrian routes so if you need to navigate by foot, the ONE will fit nicely in your hand or shirt pocket. Just watch out for the battery life which is a little short at about 2 hours.


Inside, the TomTom ONE is powered by a SiRFstarIII chipset. This now legendary chipset is known for fast signal acquisition as well as keeping a fix in locations that can be challenging for other devices. In Europe, some are now shipping with a Global Locate chip, but these chips haven’t yet appeared in the USA devices, probably due to the current legal feud between SiRF and GlobalLocate.

The ONE is powered by 32 MB of RAM and a 266mhz processor. This brings up our second issue with this device. Often when searching through long lists, especially city names, there is a long delay between typing in a letter and getting feedback from the device. There are other parts of the interface that were sluggish too. For example other devices in this class can calculate a route from the Atlantic ocean to the Pacific Ocean in about 20 seconds while the TomTom ONE took exactly one minute! three times longer. On routes of more typical lengths the calculation happens plenty fast enough, but overall the system could use a little more speed.

Routing to an Address

Routing is pretty simple. You go to the ‘Menu’ and select ‘Navigate to’, ‘Address’, ‘Street and House Number’. You can also navigate to a City Center, a zip code, or an intersection. The first think you are asked for is not a state like many other devices, but rather a city. This has its positives and negatives. The positives are that it can save time entering in addresses, especially if the city name is obscure.

After selecting the City, you enter in the street using the same search function. Here is where the TomTom search functionality really shines. Let’s say you are looking for what you think is called “Alard St”. However the correct spelling is “Allard St”. Unlike most other GPS devices, if you type in Alard you will still find Allard. Bad spellers, rejoice! The TomTom ONE doesn’t force you to be a good speller! The same flexibility applies to city names.

Finally you are asked to enter in the street number. I wish the device prompted you with the range of available street numbers. However this GPS does give you a hand. If you enter a street number that is out of range of acceptable values, the closest acceptable value is entered in which you can then select.

Routing options presented are for the Fastest Route, shortest route, avoiding freeways, a walking route, a bicycle route, or a limited speed route. This should satisfy most every type of routing you might want on the road.

You can also specify if you need to arrive at a particular time. The ONE will then show you how far ahead or behind of schedule you currently are.

Routing to a POI

Navigating to a POI gives you several options. You can route to a POI near your current location, near another city, near your home, closest to your current route, or closest to your destination. This flexibility is really handy, especially since you can add these points as via points to your route. You select how far away you want to search, and then select a category. Unfortunately, the categories are not setup in any hierarchy! only alphabetically. So while you can select ‘Restaurant’, you cannot select ‘Japanese Restaurant’. Phone numbers for POIs are also not displayed, possibly to save space on the 1GB card with the maps/POIs.

Status Display, Voice

While navigating, an arrow indicating the next turn or intersection type is displayed. Also included are fields for the distance to the next turn, the distance remaining in the trip, and the estimated time left in the trip. So yes, while the Nuvi can’t answer “how long until we get there” without doing the math yourself, you will know the answer from the TomTom ONE. It will also display the GPS signal strength and the estimated time of arrival. You can also customize the display to show other fields such as your speed.

Like most other devices, the map can be displayed in 2D or 3D modes. In 3D mode, as you approach an intersection the TomTom ONE will zoom in on the intersection and highlight the desired path. While it is difficult to measure “how well” one device might zoom in versus another device, The TomTom ONE always seems to display the maps at an appropriate zoom level, taking into account your current speed and distance to the next turn.

The volume is acceptably loud, and the voices are extremely clear. While there is no text-to-speech on the ONE, I didn’t really feel like I needed it since the prompts were clear, timely, and the display allowed you to get the information you needed at a quick glance. One thing that really impressed me about the TomTom ONE was how it will often give you not only the current instruction, but also the following instruction if it will happen soon after the first turn.

For example several times I would hear an instruction like “At the end of the road, turn right. Then turn left”. These types of instructions can be very valuable in tight areas. There were even times when it would say “turn right, then get in the left lane” in anticipation of the next turn being to the left and knowing you were on a multi-lane road. These types of instructions can be extremely helpful when you really don’t know where you are going.

Avoiding Roadblocks, Streets, Towns

This is another area where the TomTom ONE (and all TomTom devices) really excel. There are many types of “avoidances” you can set. If you are taking a “Sunday drive” you can “calculate alternative” which will take you to your destination in an entirely different way than originally calculated. Often when going on a short family trip I will navigate to a POI, then on the return calculate a route home and then “calculate alternative” to take me home an entirely different way than I came.

You can also “Avoid Roadblock”. Very sensible lengths of blocks are displayed for you to choose from; 100 yards, 1/4 mile, 1 mile, and 3 miles. You can also “travel via” to add a via point to your route. You can select from your favorites, an address, a recent destination, a POI, a point on the map, a set of coordinates or several other types of locations.

You can also avoid a specific part of the route. This feature has come in handy for me several times. You can select a specific street to avoid, and the GPS will calculate another way around. Something that I use even more often however is to avoid a specific town. If for example you are driving from Hartford, CT to Washington, DC you will likely get a route directly through NYC!. probably not what you want to do. You could use this to select a certain city to avoid and the TomTom ONE will route you around that city.

Multiple Destination Routing

Once again, as far as advanced navigation functions go, the TomTom ONE has this functionality nailed. We won’t get into a ton of details about this functionality here since we have an article dedicated to TomTom Itineraries, but here are the highlights.

If you need to visit several destinations in one day and combine them into one route, you can do this through the Itinerary Planning system. Here you can create a list of individual waypoints or destinations to be added to your route, building everything up into one big route. Here are a couple of tips.

First, don’t forget to add ‘Home’ as your last location if appropriate. Second, when setting up the route I like to add each via point as a waypoint (versus a destination) and then add ‘Home’ (or my hotel) as the final destination. In this manner I can look at the summary of the route and know how long it will take to drive the entire route. Therefore I can tell if I might be able to squeeze in one more location or if my route is too ambitious. Then, when I’m ready to set out I convert each location to a destination so that I get an accurate status and estimated arrival times to that next location.

Planning in Advance

This is another feature I wish more GPS devices would incorporate. If you are using your GPS to plan a trip, you most often want to find out how long it will take to get somewhere before you are packed and sitting in the car. Sure, you could use an online service like Google Maps or MapQuest for that, but you might not always have Internet access where you are planning your trip. You own a GPS so shouldn’t you be able to look at a trip ahead of time?

Enter TomTom’s Advanced Planning feature. This is really simple, it is basically just like creating a route to an address or a waypoint except you also specify your starting location. I use this frequently with airport travel. Let’s say last week I flew from Boston to Orlando. Before leaving Boston I want to know how long it will take me to get from the Orlando airport to my hotel. I use the Advanced planning function, set my ‘Depart from’ by looking up the Orlando Airport in the POIs, then set my destination by looking up the Hotel in the POIs. I can then look at the route summary and see how far the trip is, about how long it should take, and a map of the route. Simple, and extremely handy.

Purchasing Guidance

There are a few features you might want that the TomTom ONE doesn’t have such as a music player, text-to-speech, and Bluetooth hands free calling. Many people, however can do without those devices. If you want those features you may wish to consider the TomTom 510 or 910 which are more advanced, but are not nearly as small and portable as the TomTom ONE. (Compare the ONE, 510, and 910.)

If you want an extremely simple device with no advanced routing functionality, you might want to compare the TomTom ONE vs the Garmin Nuvi 350 which lacks many of the advanced functionality, but because it doesn’t have it some people find the Nuvi simpler to operate since there are not as many functions.

But it is really hard to go wrong with the TomTom ONE. It is a very portable device with a great screen, and all the advanced routing functions you might need.

  1. i just received a tom tom xl 325 se as a gift, first day using it and it got stolen from my truck. i was wondering if anyone knows where i can locate the serial number on the box so i can turn it into the police since i do not have the gps, just the box and all the paper work. or any other numbers that would help me out incase they do find it.

    Jasper - January 2nd, 2010
    • I don’t believe the serial number is anywhere on the box.

  2. I just purchased a used “excellent condition” tomtom One LE online, haven’t received just yet. Can you tell me what year map it has installed on it? There has been some major hiway changed in the St. Louis area, took 2 years to complete, How soon will an update be available for download to include the new routes? Since I am not the original owner of this device will I have trouble reregistering the item and purchasing downloadable maps?

    Robyn - January 6th, 2010
  3. I have a garmin bean bag and a tom tom gps device. Can I make these two work together?

  4. Our tomtom 125 tooks us an adventure when traveling between phoenix, az and tucson, az (arizona-sonora dester museum). instead of keeping us on the highway to the designated exit, it took us off the highway 25 miles from that exit through a run down reservation town of Marana. It was the scariest drive ever and I grew up in New York City.

    Is there a feature for most direct or stay on highway for as long as possible? both the fatest and shortest settings took us through this mess.

    nick - March 29th, 2010
    • Nick, the TomTom 125 (which isn’t the model being discussed on this page, FYI) doesn’t include TomTom IQ Routes so it will produce some strange routes from time to time.

      Tim - March 30th, 2010
      • Thanks for the response and I apologize for posting that here. I had a few too many windows open 🙂

  5. Dear Tim
    After purchasing a tom tom one 3rd edition from my wifes cousin for a reasonable charge,I stumbled apon this page which to my good fortune led me towards your vast knowledge of these techy machines.
    Firstly may I explain that I am a complete novice to tom toms and the like,I usually rely on my homing pidgeon instincts lol.
    My main question is,this machine I have here is preloaded with UK and Ireland maps,so,can I Purchase european maps and put them on?,and if so,do I need to save the uk and Ireland maps or do they come with the european maps?. sorry to sound a bit thick in this department,,,,but I am learning

  6. Does anyone know how long the life of this item is generally? we have had one for about four years and it died.

    sarah - May 1st, 2010
    • Four years isn’t too bad IMHO. That is four times longer than the warranty of a new one, and probably not out of line for an inexpensive consumer electronics device.

      Tim - May 1st, 2010
  7. I am going to be travelling in Europe – almost entirely on foot/train. Are any of the Tom Toms useful in pedestrian/walk mode for this purpose and how would I charge it if I do not have a car or laptop?

    Narelle - August 15th, 2010
  8. I have lost the power connector cable (from Tom Tom to dash lighter accessory). Can I buy it from you and if so how much is it.520 750 8857

  9. Purchased a tom tom one about a year ago, my unit screen froze up. Called customer service tried to troubleshoot. Worked with two very helpful reps. 3rd one I worked with, Jennifer, very rude, automatically told me out of warranty – can’t do anything, without having any information from me. Shocked that they will not stand behind a product that is just at its warranty period. Will not recommend to anyone.

    tina - September 7th, 2010
  10. When it works, it’s great, but unfortunately, it has been so much trouble that I will never buy this brand again. The people in Customer Service are great at trying to fix it, but the product is the worse, or at least mine is. The map continually freezes and it has even given me incorrect directions and does not give me the right directions even when I did not follow the GPS route. I have sent it to the factory twice and I am now on my third unit and it still doesn’t work right. Sorry, TomTom, you’ve lost a customer here…

    • I am the owner of 2. Before it was stolen from my car, and after dropping it several times, usually on pavement,my first one worked for 21/2 yrs without any problems, except for one time when I got a frozen screen with black and white veritical lines. Since it has no battery access or reset button and because it could not be turned off, I threw it in the back seat, found the screen blank(battery discharged) the next morning, plugged it in and it worked without a hitch about 9 months prior to being stolen. I used it every day 5 to 8 hr/day as a courier driver. Perfect it ain’t but with the tips from here and for the money, the 130 does the job. The new ones are better…much longer battery life, Kudos to Tom-Tom. No machine is perfect and there are ways to work around the destination and directions issues.

  11. We’re in Florida, and left instruction booklet home. The system is making an intermittant “mooing” sound, and has an indacator that looks like a comb on the left, and a bell. I can’t figure this out, and can’t seem to get it to stop. Please help. Tks, Mike M.

    Michael McGonigle - February 2nd, 2011
    • This is the radar alert. It means that there is a radar in the area. To stop it, click on TomTom Services (usually the second screen of the Main Menu) > TomTom Safety Cameras > Disable Alerts.

    vicki - February 8th, 2011
    • I don’t know of any places that perform in person map updates. The application you will need to purchase and download a map update can be found at http://www.tomtom.com/home

      Tim - February 8th, 2011
  13. I have a TomTom One and I want to know if business card information can be added to it. I have a lot of business cards that I carry around the would like to put them in the TomTom.

  14. I am a long haul trucker and use a Tom Tom One in my car. Can truckers’ maps and instructions be downloaded to my Tom Tom One? The truckers’ GPS units are quite expensive.
