We are not sure that all Gps Garmin are compatible with the maps inside our web site and in all the web. Here below we suggest you a list about Gps that are, for sure, compatible because already tested by us or by our web site's visitors. You will find inside the list Gps actually in production and Gps not in production any more by Garmin. The list below is continually updated. In theory, if the Gps is Garmin and if it is based on Mapsource, the maps must work, but on the last generation Gps, as Nuvi, we have some doubt. Moreover, if the map has been uploaded on the Gps before your purchase and if you have not the CD of Mapsource, we think that is impossible for you to work with our maps. If anyone has news about this subject, please inform us so we can update the list here below.
