If I still have the 5 and 6 mapsource/city select installed on the pc, which was for my Garmin V, can it be used with the Quest? or do I need to uninstall and then reinstall the new mapsource?
And after trying to read the manual, (don't know why I bother) do I need to install (on the pc) the mapsource for the Quest or is all the mapping that comes pre-installed in the unit, enough to use? what is the c/d mapsource for, does it have greater detail, than the pre-installed mapping.?
