Burned CD's are a thing of the past now.. I'd rather hook up my zune or phone. I'm not in my car enough to make use of satellite radio.

The Shaker 500 is a quirky piece. Sometime ago, I stopped at the gas station, had a CD playing, shut the car off, fueled up, started the car, no sound whatsoever from the shaker. Didn't even seem like it turned on. Got to my next location, when I got back in the car, started up and the shaker was back. No explanation and hasn't happened since.

 

Its the CD-R syndrome.
They are thicker and tend to
delaminate at high interior temps like
your mustang on a hot sunny summer day with
the windows rolled up...

Ditch the zero (sheitter)
and get with the hero (pioneer)
