I have a 07' CTS Sport, and wanted to put a navigation system in it. I would like to still use the controls on the steering wheel with the system. Do I have to go through Cadillac for this, or is there an aftermaket product I can buy.

 

you dont have to go to thedealer for this...they have many different modules that will allow you to use the factory controls with aftermarket products......call mike at 305-478-8473 he can answer all your questions
