Sorry if this is a duplicate thread, I've tried to search through both the forum search and on Google, and can't find an answer for this.
I have a nuvi 750 that I've had for years now. I've gone through several iterations of map update software, and the unit originally came with only the stock 49 states maps. Around 2012 or so, I purchased the Amazon nuMaps Lifetime North America (USA, Canada, and I think some of Mexico if not all). I recently had the need to use the GPS again, so I went to update it and found that the only software that shows on the my.garmin.com is the Garmin Express application that's supposed to have all of my map software (each map license/code is listed there and next to it is the same link to Garmin Express).
Well, the Garmin Express app only shows the Lower 49 and not my nuMaps (even though the website shows it and has all the info about it). My original computer, that I had the old map update software on, died; but thankfully I still have the "Garmin Map Update" software that contains the installer that lets me choose the map I want to install (it accurately shows both the Lower 49 and the NA maps).
Before I figured out how to get the old app to work on my backup of my old files, I used Garmin Express to load the map update (lower 49) and it did allow me to switch maps, but none of the choices actually contained the entire continent of North America--I could only choose option like West, East, Canada and border states, etc.
After I used the Garmin Map Update software, it prompted me to install the Garmin Lifetime Map Updater. This software shows the new map version (2015.40). When I plug the GPS back into the computer with Garmin Express, it doesn't even recognize the nuMaps North America, and says there's an update to the Lower 49 (2015.40).
I really don't know what to do at this point. I suspect that if I allow it to install the Lower 49, it's going to overwrite the map version that I have, which includes Canada. I also don't know if there will be like a 2016.50 version next year to the North America map, and if the Garmin Express will be able to do the update (or am I just stuck with the Garmin Lifetime Map Updater?).
Does anyone else have this problem and was able to successfully fix it or know what's going on?
