Wow, $300 for a Bluetooth adapter? I mean it does look easy to use, but dang.
I had an aftermarket head unit installed in my car that included Bluetooth. My car doesn't have steering wheel controls. I'm not sure if that's an issue on your car, but that's normally an extra harness they can install.

My car didn't come with Onstar from the factory. So, I used the microphone that came with the Head Unit. I ran the cable up the A-pillar and along the liner, then stick it next to the rear view mirror.
