I'm wonder if the Pioneer Navigation still use steering wheel controls? Also with it work with a Bose system? Trying to decide on one of these two:

It can work with the steering wheel controls but you need an add on module.

No the bose won't work. If you want bose and navigation and simlicity then go with the GM TNR or INR Nav system.

Look up at the top of the Electrical section, you'll see Ben's FAQs about adding aftermarket radios, and what modules you have to add to make Bose and the steering wheel controls work.

ON EDIT:

I knew I had seen this before.

Here is an install thread from another member. He describes exactly what you need to do.
