Yes, I was frustrated with the process and my ignorance dealing with this, by no means frustrated with the help you've been providing.


With that said, I was able to successfully install OSM maps on the computer AND upload it to the GPS!

First downloaded the exe file, installed the OSM .exe file, then tried the MapInstall software. No go here, it detected my GPS unit once connected via USB but it said "no unlocked maps found" and no way out of the opening screen.

Then I tried Mapsource; i had to play with the menus to understand what was going on, it took me a while how to load the Mexican map then send it to the devide.

Checked the GPS unit and yes, the Mexican map is there!


Now I have a follow up question, since my "base" map for the USA is from 2008: would it be hard to try to update the US map as well and replace the City Navigator 2008?? I understand I can't fit the entire USA map on the device.

Thanks again!
