JAZ, suggest you check with crutchfield or a stereo shop to see what is available. Usually there are aftermarket adapters that allow you to keep steering wheel controls with new head units assuming the head units have the functionality that the steering wheel controls are for. In the last year or so, I have replaced a couple of factory head units. On one, I had steering wheel controls for volume, mode, tuning, track skip, etc. I bought a head unit that added bluetooth as well. I had to wire in an adapter to the wiring harness that allowed me to use the steering wheel controls with the new head unit. On the other, I didn't have steering wheel controls but the vehicle door chimes, etc. played through the car speakers, so I had to wire in an adapter that allowed me to keep that stuff also. Have no idea if such an adapter exists that allows you to keep steering wheel controls and also the phone pairing and factory bluetooth mic, but it very well may exist. If it does, crutchfield can tell you and will usually sell it to you half price if you buy the head unit from them.
