does the stock bose system in the touring have an AUX input in the back?

also.. Is it possible to purchase and install the stock Nav system and add it on to the bose head unit if you didn't get it with the car at purchase and does anyone know if you can watch DVD's and use voice recognition??

 

The only HU that has an "AUX" is the units with the SAT option. Its basically another line in. So if you have a SAT compliant HU you can use that for another input like a DVD or another input source. If you have an 03 like myself your only option that I'm aware of is FM modulation. This is better IMO because you don't get the crappy sound usually found like when listening to CD's, the Radio is usually clearer.

Don't know about the rest.

 

Yeah i've heard you can get decent sound by actually plugging into the FM in back...

I'm just not sure what I want to do at this point... I want voice rec. Nav, and DVD, along with good sounding audio but I do kinda want to keep the 6-disk stock if possible... but something tells me I'll be tearing it all apart
