hey guys...i've been wondering this for a long time.
it's probably been discussed a million times so if there is an appropriate link please pass it on to me. thanks.

can i install an aftermarket headunit that will work with the steering wheel controls and not interfere with the voice directions of the Navi?

also, can i use it in conjunction with the factory bose subwoofer...i'm not going hella crazy on the ice...i still need my trunk...

thanks in advance...

 

Nope not unless u plan on tapping into the face or after market head unit buttons that control the volume track number and all that. or if u can get an aftermarket radio made for ur car to run with the buttons, lol lots of money involved there.
