I have a Stiletto 100 and I have used it with both the FM transmitter, and the vehicle kit that goes directly to your radio via the antenna cable, and both have terrible sound quality when you compare it to regular FM radio, and the volume is very low.

Is this normal, and do all of the other Sirius radio have this same problem?

I am considering buying a new unit and I wanted to know if I will get better sound quality with a different unit.
