G4 & Radar Detector
To add a little more info. I have experienced the loss of satellites two or three times on my Montana. It has just enough to be a minor irritation. I am using a G4 and a radar detector. On my last 1,000 mile trip, I experienced it for a very short time. The radar detector was not on at that point since I was in Virginia. Whatever is going on is intermittent with me.
