Hello everyone searched and haven't found a real answer
what factory stereo does support bluetooth music streaming on all speakers? I have the pt546-0100 on my tC with the crappy BluLogic bluetooth factory installed that streams only on the door speakers

If i swap it do i need aditional wire adapters ? Can i use the same microphone that comes with te one i have now ? Can i do a swap with another factory unit that doesn't need any modifications ?
thank you
