I installed Factory Radio parts for many years when I was a GM technician, So I know it's a quality product. I installed Radio and works like new, other than the Aux port is only operational on the FM band. Regardless of the input the sound quality is similar to any other FM wireless adapter that I've tried. I've tried it with an iPod and a bluetooth adapter plugged into the AUX port on every FM freqency ( some are worse than others). Sound is low and degraded, radio volume has to be turned up to nearly max level to listen at a normal volume level. Sound levels are normal when listening to FM or XM. Overall I'm happy with the price and the quality of the reman unit. The Aux port is disappointing for me though.
