How do you update a nextar x4-t gps with new updated information?

To update the existing map for your Nextar product, please contact Nextar to find out if any new map information has become available. The products are usually pre-loaded with USA/Canada maps, depending on the model.
OR
Go to Nextar.com and select your model.

i've owned the unit 2 years now and not 1 update has been released, very unhappy but unit has worked well.

Well, that is going to be near impossible.

You can TRY, with no guarantee, to find out what map company makes the maps for your Nextar. It's either IntelliNab or Odyssey.

Then you would have to load new map data direct from those map companies onto your SD card and pray it works.

From experience it usually ends up crashing the GPS. If Nextar doesn't offer an update, then you're probably out of luck.

Require updates for Nextar 14-BCT GPS

Contact Nextar personally and request that free upgrades be made available. This is my review I tried to post on Buy.com.

After working with high end GPS units for six years, using the Nextar X4-T was my first exposure to a consumer grade product. While this unit is very easy to use out of the box, the accuracy of the vector data and the quality of its supporting database leaves much to be desired. Some of the data on this unit, particularly around my home, is at least five years old. You would need a bulldozer to reach my house following its instructions. In addition, the current 911 rural street address for my home does not exist in this unit and I've been at this location for 10 years. If an emergency responder was depending on this data to reach a location to provide life saving assistance, where every minute counts, I afraid it could cost someone their life. I realize that creating this type of data is time consuming and costly, but I also know that better data exists and is available. Unfortunately, after contacting Nextar and requesting updated data, I was informed that it was not available. Nextar purchases their data from Navteq just like Garmin which has 2008 and 2009 data available. I believe Nextar should provide the most current data available to their customers at no charge and that Buy.com should require that they do so or quit marketing their products. [email protected]
