Hey Guys,
I just bought a 2003 G35 with Nav. The former owner had the Bose replaced with a later model ( I think 2004 ). I took it apart and all connections are OK except for the Nav male coupling, it is different from the female coupling on the Bose. Not much, the Bose is slightly wider than the car coupling.....
Any suggestions?

 

Early 03's have a slightly different radio from the rest, so you might be out of luck.

However, factory nav sucks anyway, you're better off not wasting your time with it.

Get a $99 garmin (cheaper than a nav update anyway) and you'll be much happier.
