Is it possible to tie an aftermarket Nav system into the Bose stereo? I have searched for a past thread but all I can find is info on hooking the stock nav to a new stereo not the other way around. Does anyone have the connector pinouts?

 

I was wondering that same thing anyone that have an aftermarket nav that can tells us.

 

As far as I can tell, nobody on this board has done this without an FM modulator. The BOSE stereo comes with no inputs. Actually, I should rephrase. I don't think anybody has even managed to do it with a FM modulator, nor do I think you would want to. People have gotten DVD audio through the FM, but Nav commands seem to typically come from a stand alone speaker.

It's awkward, but I'm not sure there's a better solution unless you replace the Bose.
