I searched the thread, didnt find what I need.
I have non XM factory head unit in my TB, been using a sirius add on, Im sick of it, can I swap in a factory XM head unit and subscribe.
Will it work, can I upgrade the current head unit for XM, should I just get an aftermarket head unit?
I havent messed with car audio for 15 yrs so Im out of the loop, will probably upgrade the speakers at some point but this wont be an all out build.
Thanks
