Garmin “Additional Updates”


This is one of those answers we give frequently, so we’ll document it here for future use. People often ask about installing additional voices on their Garmin devices, or where the firmware updates for traffic receivers are found. The answer lies within the ‘Additional Updates’ section of Garmin’s WebUpdater program. Part of the confusion stems from the fact that the Additional Updates are not displayed when you first connect the GPS if major application updates are available for the device itself.

Garmin WebUpdater Additional UpdatesSo the first time you run WebUpdater it checks to see if there are any major application updates. If those are available they will be downloaded and installed. (If no major application updates are found then it will show you the Additional updates at this time.) Next, you disconnect your device, reboot the GPS, and then connect again. Provided there are no further application updates to install, the Additional Updates section will now appear.

So what types of updates appear in Garmin WebUpdater in the Additional Updates section? Things like additional voices, voices for different languages, firmware updates for traffic receivers, and updated translation files to draw the user interface in different languages. Most of the time people will be looking for voice updates and traffic receiver updates.

  1. One thing that is not apparent from “Additional Updates” is how to tell which version you have or whether you need it.

    For example there is a “GPS Chipset Type M” update with no version or change history and no idea whether I need it for “my” nuvi 750 (or only others with different chip)

  2. If the update appears in that section after scanning your device, then the WebUpdater program thinks your device needs that update. The updater program can determine which chipset type is in each GPS, so if you see the update there, Garmin thinks your device needs that update.

  3. I just bought a Garmin 260W. The first “test” I ran was on two addresses for neighborhoods built 3-5 years ago. My 260W was loaded with 2009 maps. Neither of the addresswa showed up on the maps. One address in the Seattle area did not even recognize the street. Anyone who is familiar with this city knows that there can be a 162nd St., Road or Place and then also NE or SW. You could be on the other side of town with the wrong entry. And I was forced to chose SW when I wanted NE. Garmin’s website shows no updates available. I’m unimpressed with the map data provided and the Garmin is being returned. Great gadget useless maps.

    • I agree with you that the outdated maps are frustrating, but Garmin buys their maps from Navteq or whoeever. And Navteq is the best out there. All GPS’s will have old maps so I don’t know what you expect you will find from anyone else.

  4. I’ve noticed my Garmin Nuvi 255W doesn’t have the on/off switch to save the battery when I don’t need to use my GPS… Is that a “common” feature?
