Just picked up a 2006, GS300 AWD with Navigation.
I'm guessing I have an old Nav Map DVD because it couldn't recognize a street
in a housing development that's about 9 years old!!
1) What Gen (generation) of map DVD do I need to be looking for. Don't want to
get a map DVD (probably used) and have it not work.
2) Is it possible/costly to upgrade from one's current version/generation of Nav system
to something newer?
Thanks
Ken
