I have a XMP3i with home kit and vehicle kit (in my work truck). I travel the whole state, and there are like 3 spots along some mountain passes and one tunnel where I lose XM reception. In other words, almost never. I just bought a new car, which came with an in dash Sirius radio and 3 month free trial. Just driving around town, and in strange places like on top of a bridge with no obstructions anywhere, the radio just stops playing and says "Aquiring Satellite". Then starts about 5 or 10 seconds later. I know the two systems use different satellites, but is this normal for Sirius to drop out regularly, while XM never does? I was thinking of adding the car to my subscription, but if its gonna drop out, Ill just get a vehicle kit for the car for my XMP3i.
