I have a brand new head unit that has been sitting in my garage so I checked and it will fit the car but the installer said I would need a 150.00 module to make the steering wheel controls work. Question is if I bought a new one would I still need the module?

crutchfield.com has all the info you could possibly need.

And the answer is yes, and Crutchfield as point pointed out has what you will need.

Crutchfield is a great source

I think the wiring adapter my guys offered me was $35 back when I installed in my LT.
I didn't have the steering wheel controls so I passed.
