My unit is a Sirius Sportster Replay.Tate Satellites said:My XM sounds great. How does your system come through your radio?
I've had it connected via line-in and via the FM modulator. The line input just managed to make it slightly louder. Quality was only marginally better than the modulator.
When I moved the unit to my new car, I retained the factory head unit and I'm now using the FM modulator.
I haven't tried an XM stand alone unit but I have listened to XM off of D* and it seemed to have the same quality issues. I'll have to get my hands on a XM unit to play with.
