What music format is it in your USB?
Bluetooth is great. When my sales advisor used it to test the audio, he could not believe how good it sounded. I could not believe either that my iphone music could sound amazing.
Back to satellite radio...I remember when I had my RX, Ireceived an offer from them for a lifetime subcription for about $600 if I remember correctly. I declined but I thought that was a good offer, although I was not sure whether that was trasferrabke if you changed car.
Anyway, I don't think I will subscribe after the free trial expires unless it is for less than $5.00 per month.
