Does any one know of resources on how to replace a factory stereo for 2006 Trail Blazer for one that allows bluetooth music streaming as well as phone calls?
What about you keep the factory radio with all the factory features working
and you add a bluetooth interface with USB and iPod controls also bluetooth for music and the phone
caller ID will be display on the factory Chevrolet Trailblazer factory radio
