I there, recently i buy i new garmin gps (someone stole the older one), the new model is Nuvi 1390T.
I recently download from garmin's website the mapsource 2010.2 update, and install it.
Now i have this folder Additions, and inside have some files, one of them are gmap3d. I need to know here install it, and how to put this working.
Another file is the lane assist can't use/or install.
Please a litle help to Portugal. Cant find answers on google or garmin website.
