I've been a longtime lurker here and just recently decided to do some upgrades. I have factory nav and of course my cd changer doesnt work. I've searched but am not finding where I can have my factory nav still work after installing an aftermarket DD unit. I have an 04 g35 sedan. Crutchfield says it wont work and a local installer said the same thing. I know I saw someone here that had both working, but I can't find it. Can anyone help with a link?

 

im looking for the same info. cause im doing the samething.

 

Surely someone here has done this. I didn't see what I was looking for in any of the FAQ's.
