Harman Kardon GPS-300


Hot off the heals of the release of the GPS 500 from Harman Kardon comes news of a newer younger sibling, the Harman Kardon GPS-300. As with most early notifications, not too many specifics are known about this device yet. We loved the GPS-500, so we are glad to see that the GPS-300 appears to have many of the same qualities, a compact slim size, a good 4″ widescreen display, as well as the ability to play MP3 music files. The one difference we do know about is that the 300 will not incorporate a video player.

We expect to see this device appearing on store shelves in about three to four weeks and the initial street prices should be in the neighborhood of $299 making it one of the cheapest widescreen GPS models available.

  1. Driving around prior to getting a signal will increase the amount of time it takes to get a signal. I’d try our Acquiring Satellites Tips and if that doesn’t help, I’d contact HK support. I’ve seen a few cases in their devices where the antenna wasn’t properly attached to the GPS chip.

  2. GPS 300 Can anyone tell me what the upgrade to the firmware actually improves, also I cannot find any instructions on avoiding places such as Paris on a planned route ?

    Dave - July 24th, 2008
  3. Just took the GPS 300 outside the front yard and stood there for a good 20 minute…Yet no signal.
    Guess i’ll be returning this.

    Derrick - July 24th, 2008
  4. Derrick – I had the same problem with the first unit I received – would take half hour to receive a signal at the best of times. Exchanged for a new one, and the new unit picks up a signal in less than 30 seconds, whether driving or still.

    Dave – I contacted the harmon kardon support about what the upgrade actually does. I was told that it only addresses a lock up glitch, and if i wasn’t experiencing that problem then it’s not necessary.

  5. How do I get updates for my Harman Kardon GPS 300??

    Mary - August 17th, 2008
    • Also are the updates free?

      Dan - June 29th, 2011
      • Harman Kardon exited the GPS business a while ago and I don’t believe they are offering map updates anymore.

  6. I just moved into a subdividion and was unabale to type in my new address. How do I update my gps 300na?

    Dianna - August 17th, 2008
  7. I just wanted to know, if it was possible to change the voice on the gps 300? I drive on average 1000 miles a week and the standard voice is begining to sound like a nagging wife.

    Daz - August 30th, 2008
    • There is a male voice as one of the settings. The downside is it doesn’t call out the street names like the female voice does.Such as “After 400 ft turn right” instead of “After 400 ft turn right onto Grand Ave”.

  8. I have posted and see 107 postings, however I do not see any replies.

    Do you ever plan to post any answers to the many questions?????????

    Or am I missing something? ? ? ? ?

    Hager - August 31st, 2008
  9. Hager, this isn’t a Harman Kardon official site. If you need product support you should contact them.

    Tim - August 31st, 2008
  10. Then what is the point of posting here? Seems a lot of people are asking for help.

    Thanks for the reply it was the first from this forum.

    Hager - August 31st, 2008
  11. Hagar, there are dozens of replies in this forum, both from me and other users. I’ve posted around 20 responses to questions. This is a free, community based site with no obligations to you. If your expectations are for something more than that, you should contact Harman Kardon support or the store you purchased the device from.

  12. i bought harman 310 in florida and im back in ireland and just wondering where i can download europe maps for free or do you have to pay for them.

    clyde - September 4th, 2008
  13. You must pay for additional maps.

    Tim - September 4th, 2008
  14. tanx for that bloke in shop told me i could just down load them had a feeling he was lieing do you know where and how much they are.

    clyde - September 4th, 2008
  15. You would need to contact Harman Kardon– I’m not certain they even offer them.

    Tim - September 4th, 2008
  16. i was just on hk site and there selling then on sd card for $150 but would that mean i would,nt be able to use my sd card with music or with the one they sell do you download the maps from that to the sat nav new to useing them had to buy one quick to find our way around florida and the guy in the shop would of told me anyting just to get me to buy and are they any use im told garmin are the best at the moment.

  17. H/K GPS 310
    Purchased a gps HK 310 and am reletively happy with it. This is my first GPS unit and I was expecting a lot of perks that maybe only the higher priced units have.
    Such as…..Speed? Is this so hard to put in the software. It needs this for the calculation anyway, so why not display it. I would like a second opinion to the officers question “Do you know how fast you were going”
    There are roads that dont appear on this unit as well. 10 year old roads. Found that odd.
    Also, can I force the unit to take a different road, or map a route different than the one offered? Maybe this is standard with all GPS. My only solution is to take the new route and the unit will remap on the fly.
    I agree with POI’s being out of date. I have a dozen Tim Horton coffee shops around me and none are in the poi’s. (Canadian issue maybe, although this is a 310NA I assume)
    Other than those wish list items, I like it. (Is that too many beefs)
    Also looking for update maps and firmware.

  18. I purchased a Harman Kardon GPS-300, when I updated it to version 01.10U, it stopped working. I contacted Harman Kardon and they told to return the unit to where I purchased it. Because it had been purchased more than three months (about 5 months) when I made the purchase they did not want to take it back. I wrote back to Harman Kardon & they refused to help. The problem is this:
    Now when I switch the unit on, a warning screen comes up in red on black and locks the screen, the serial number displayed at the bottom is #0000-0000-0000. I tried re-installing the update again, all to no avail. I know about the three different ways to reset the unit, nothing works. All attempts to re-install the update have taken me as far as the page where you can set the time, once you try to go pass that page, the unit reverts to what I have described above. Can anyone help with this? I was looking on the Web for the original firmware but could not find it. By the way I also try the recover from card that also did not work.

    Roger - October 12th, 2008
  19. Mine did the exact same thing, I had to take it back. I was lucky and it hadn’t been but a couple of days since purchace. I personally tried the update 20+ times with no avail. Sorry but I wish I had better news for you. With the one that i got in exchange, i did NOT run the update, screw it.

    Zach - October 13th, 2008
  20. Thanks for the info Zach, I have purchased several GPSs, I tried all major brand except Sony, I currently own seven Garmins (Gramins have never refuse to help when it was needed). Harman Kardon would have been better to help out, I was responsible for a few sales of the GPS300 but now no one I know will ever purchase another Harman. I hope that someone else will have experienced the problem with the GPS300 and offer me a solution.

    Roger - October 13th, 2008
  21. Hi Tim, Steve, or anyone with some answers…Hoping to finally get some info I did not see addressed above in previous entries.
    1. Seems doing the update to 1.10U presented some problems with the 300 NOT working afterwards, according to Roger and zack? Is this a real problem, particularly if the unit is about 6 months old? (I prefer the lower risk approach.)
    2. Is the small gold recessed hole in the backside indeed the place to attach an external antenna, assuming there is one available…and if so – where do we best get one and how do we do the install?
    3. Finally – on my GPS Data page, Elevation is ridiculously in error. I am about 200 feet above sea level, yet the elevation number shows a -927 feet. If I use the paper clip idea in the reset hole, do I need to be doing this at sea level AND with the unit on, or should the unit know where I am from GPS coordinates? If THAT is the case, I would therefore also assume the coordinates are “out to lunch” for the elevation to be so far off.
    Thanks for any help you may offer :-)!

    RobertM - October 18th, 2008
  22. 1) I haven’t updated a 300… but I’ve updated a 500 without trouble.

    2) Yes, you can attach an external antenna there– the port type is fairly generic so most any external antenna should do. For installation you just plug it in.

    3) The GPS system doesn’t provide very accurate elevation readings. It is designed primarily for horizontal measurements. That seems a bit further off than most– but there isn’t really anything you can do about it. You can’t “zero it out” or anything like that.

    Tim - October 18th, 2008
  23. Thanks, Tim.

    From the looks of the small hole on the back, it is not clear how an antenna would mount or remain affixed. Any suggestions?

    And secondly, might you have a source, website, or store suggestion for such an antenna and is there a specific design to ask for?

    RobertM - October 19th, 2008
  24. The antenna just gets attached by friction. You press the end of the antenna cable in, and it is held in place by pressure/friction. I’ve used this antenna with the HK 500, I’d assume the same antenna would work with the 300.

    Tim - October 19th, 2008
  25. i rang harman kardon in usa from ireland to try and purchase sd card with europein maps and they told me i need to be living in usa with a usa credit card to buy the sd card can anyone tell me why this is as im back in ireland, if i was told this when i bought the gps i would not have purchased it. guide+play gps-310

    clyde - October 19th, 2008
  26. 4-GB SD cards are pretty commonly available on the Internet, and in that case you should be able to buy any card you choose from your home venue just like any other purchase. As far as I know, 4-Gigs gives you plently of capacity for any updates or music downloads and the only criteria is to not get a “super” fast card, as it might not be read propery. Just the standard SD card does the trick, from what I read, and as far as I know, you do not need to look for one that HK makes or is proprietary for their use.

    RobertM - October 19th, 2008
  27. to robertm tanx for info so if i get sd card is there i site that i can download the maps for europe to put on it.

    clyde - October 19th, 2008
  28. Now there you’ve got me since I haven’t done that myself. But I assume that may need to come from HK, unless Tim might know if the map program they use is some universally available program that also works with HK’s 300.

    RobertM - October 19th, 2008
  29. would you be able to find out for me and let me know cause im thinking of buying a new one but if i can get maps of europe il do that before i pay out for new one and just have the one i have doin nothing. tanx clyde

    clyde - October 19th, 2008
  30. Any new or updated maps would need to come from Harman Kardon and to my knowledge none have been made available by them.

    Tim - October 19th, 2008
  31. they have them for sale on their site for 150 dollars but as i said when i rang them they told me i have to be living in usa with an address and credit card their so with me living in ireland do you know why they wont sell it to me or is their else where i can purchase one.

    clyde - October 19th, 2008
  32. Any new or updated maps would need to come from Harman Kardon.

    Tim - October 19th, 2008
  33. i understand that but they wont sell it to me cause i dont live in the usa and just wondering why not

    clyde - October 19th, 2008
  34. I don’t know– you would have to ask them why.

    Tim - October 19th, 2008
  35. ok tanx for your help ill give them a ring tomorrow and see what they say

  37. hi, just purchased the h/k gps 300 in germany but need to be in greece for a while and drive around al ot. can not find a thing to run the greek map on the net. help anybody?

    Adonis - November 10th, 2008
  38. From what Tim has said previously, the 300 may be a bit new to expect map updates of any genre or perhaps even maps that encompass different global locations. In any case, if I understand the updates issue, we have to be careful that any map update will run on the HK software, so it sounds best to wait until HK releases maps designed to work on their product.

    RobertM - November 10th, 2008
  39. Hi Roger (Comment 118), did you have any luck with your problem? I did exactly the same thing with my gps500, downloaded the software, installed and now i have an expensive paprerweight. HK are not interested. I wonder if someone could upload a copy of there resident drive, i might be able to reinstall and go from there…..long shot.

    chris - November 30th, 2008
  40. What happened with Harman Kardon website? I am trying to find their site to look at updates about the gps-300 but its not available.

    But fromw hat i see here might be a good thing they are not online anymore.

  41. Just bought a GPS 300 yesterday. I’m just glad I read this forum before finding an update and installing it. So far I’m really impressed with the unit. I’ve only used it around Swansea which is where I live. I know of new road layouts that have been set in place for just over a year and they’re not on the mapping of the unit. Going to Halifax in a week or so, Baveria in the summer so will be keeping fingers crossed for success!

    This is my first ‘Satnav’ unit so I don’t have anything else to judge it against. Having looked around for other Harman Kardon products, they seem to make/provide some high end spec equipment. To that end, I’m surprised that they’ve been less that helpful with people’s enquiries, questions and complaints.

    I bought mine from one of the Cash Converting shops who told me they bought units from refurbished stock! They gave me a six month warranty so I’m happy with that. Knowing my luck it’ll go belly up in six months and one days time!

    I’ve added this forum to my favourites and will be checking back here regularly.

    Read a quote from another site that reads, ‘The bitter taste of equipment failure lingers longer than the sweetness of a cheap deal.’

    Lets hope it doesn’t ring true in my case!

  42. what is text to speech? Is it the same as the gps says out the street name?

    Dikshan - March 24th, 2009
  43. I have had this GPS unit for a few years. Well let me rephrase that I had the first one for about 9 months, then this other one for just over a year. The first one constantly got me lost, took forever to load until the power slot broke off inside the unit. When getting it replaced, I got a lot of arguments and rude customer service from the warranty dept. in NY. Finally when getting my new unit, it worked perfectly for about 3 months, after which, it started freezing in mid route, would not reset unless you used to resent button about 4-5 times, sometimes would just decide to not power on at all. As of today, the solder points on the power port broke again, and instead of spending the money to repair it. I’m getting a new unit. I would NEVER buy one of these Harmon Kardon GPS units again. I spent A LOT of money on a piece of garbage.

    Justin - April 19th, 2009
  44. I just bought one of the gps300.When i turn on,and touch the screen its keep show me the padlock,however the lock switch is turned off,tried everything……..even the update,but when i turn on and got into the service screen,im unable to tap the update from sd card button….because the problem.Anybody?

    Beelzebub - April 29th, 2009
  45. I am having the same problem that Roger had! I updated my gps-300na to v1.1 and now it is a brick. HK support was no help at all and since it is no longer under warranty it appears I am out of luck. Anybody had any luck getting this problem resolved?! I’ve reinstalled the update numerous times and it always gets stuck after I fix the time and hit next. My serial no. becomes all zeroes and it freezes! Help?

  46. I’m going to use my computer USB cord to charge the device instead of the wall unit. Dumb question: Should I charge it while the device is ‘OFF’ (which I do), or charge the 300 unit with it ‘ON’?
    I know…strange question. Just making sure.
