But for the indefinite future, don't use MapInstall for any recent nuvi, especially if you want to keep its special features.įor over a year, I've been told by everyone at Garmin and everyone here to use Mapinstall to install maps. This is required due to the age of the 650 due to its limitations with current maps. Note that you have used MapInstall on your old nuvi 650 with a SD card to be able to have all of North America available between the nuvi and SD card. Like sussamb, I can't understand why you tried using MapInstall to 'reinstall' an already present map on your device.įor future use, only use Garmin Express or GarminMapUpdater to update maps on the 2797 and never use MapInstall. If the current map is missing, reinstall it with Garmin Express. When done, check your free space and check to see if you still have a functional City Navigator 2017.10 map on your device (go to the nuvi's myMaps page and tell us what you see and what's checked). Supplemental map files will be along the lines of gmapsupx.img where the 'x' can be another 'p' or a numeral.
My suggestion (and I urge you to wait and see what others say) is to search the nuvi 2597 for supplemental map files and to move them off the nuvi and keep them on a computer in case you need them again. MapInstall only updates the map file itself, hopefully with the unlock file as well but you're seeing a problem even with the unlock file.Īnother reason to never use MapInstall to update a Garmin device's map is that MapInstall creates a Supplemental Map and these maps need to be manually deleted as they will not be auto-deleted during a future map update. If you want to keep features like Junction View, Voice Recognition, etc., never use MapInstall to update a map on a Garmin device with these features.
