Ages ago, probably back in the days, someone (sorry I don't recall who) shared this 3D model they made specifically for Garmin GPS devices. I just happened to find this and thought at least 1 other person out there might still be holding onto a dedicated GPS device like myself and enjoy using it. Just drag and drop this *.srf file into the "Vehicles" folder on your Garmin and you are good to go!
