Howdy, I have a 2006 LTZ that does not have an Aux jack or Bluetooth in the radio. I was looking to add them in but to do so with a gateway device is going to end up being $150 - $200. I'm wondering if it would be cheaper to just buy a new stereo that already has these two things built in. My main question is, is there a way to replace the factory stereo and still maintain use of the steering wheel controls for volume, radio tuning, etc. I don't know how all of that interfaces together but usually see people saying you lose the wheel controls if you replace the stereo. Just didn't know if that's always the case or if there's a way to connect them to the new stereo and make them still work. Thanks!
