In looking at the threads in this section can I safely assume that you can put in an aftermarket headunit with a bose system and not have any problems, or do any modifications? I want to add a Sony headunit with front imput and usb port. Can I just take out my stock headunit and put in the Sony without doing anything else other then changing the wiring harness? Thanks for the help in advance.

im in the same boat as you
my old bonny i had a stereo in
but the new one i dont know if it will work
i took mine apart adn there is the same 3 wire and there is one extra wire
the wire is for the stereign whieel control
and it didnt work with you it in
so youmight just need a spection connection for it or you mihg tneed a specal headunit
hopes that helps

anyone?
