So I have presets for all 6 on xm1,xm2 and xm3. When I turn off my car say I will be on xm3 channel 6 pop 2k. Ill start it later and it will be on the preview channel that says call xm 1-800 whatever. It happens random. The other day I was driving and went from xm1 to xm2 and preview channel. I know not a big deal but annoying. I checked with xm and they resent signal or whatever. Dealer replaced antenna and I dealt with it for awhile but on the drive to Atlanta the reception sucked and it did it often. Dropped the car off 2 days ago and they cant duplicate. Anyone else ever experience this.
