I don't have too many problems. It does lose signal easier than my other cars XM but still isn't very often. My XM keeps signal even when driving beneeth overpasses etc. I believe the issue isn't with the signal. It's with the receiver or antennae. With my XM I can unplug the antenna and the stereo won't stop playing for up to 30 seconds.steveb said:Has any one noticed how easy Sirius seems to loose the signal, even when just going down a wide open road?
