i have 03 sc340 with nav... my girl drives mostly in south oc area. She has been realizing that some of the south oc areas are not updated on her nav info. Is there a way to use 04 gx470 nav dvd??? i can make a duplicate copy with a dual burner.... or is 03 a CD version or different model of nav brain??? any other way other than getting ripped off at the dealer for a update Nav disk?

 

first of all please don't talk about copying dvd, that's privacy issue and we don't allow those topics here

and regarding 04 gs470, i THINK they share the same system, but i am not sure if you can just stick in the gx dvd. you might need an upgrade dvd
