tried Sirius Radio for several months as it came with my car. Very poor audio quality. I tried to like it - couldn’t do it. Did not sign up for the subscription. Fortunately, my car stereo has a USB port. I just plug a flash drive in - presto, great music quality. I have lots of music, and keep several flash drives full and in the car for variety. Better than any radio station, no commercials, great audio quality. That’s all I need in my car.
I am a jazz and classical music fan and the musical offerings on Sirius/XM are pathetic. I find that my local public radio stations have a better selections of the music I want to hear. Pandora is a great option and would be worth the subscription if it were offered on satellite radio.
