I just recently installed an x920Bt with a GEX920xm tuner. I've had XM and sirius before so I know what's acceptable as far as the signal dropping out when going under an overpass. The installer placed the XM antenna on top of my dashboard right where the dash meets the windshield. I made a 3 and a half hour trip to Pennsylvania for Easter and it cut in and out way too much, even when on an open road.
Is that considered a bad antenna location? What would be a better location to move it to? For the record, I drive a 2008 Ford Escape SUV.
Thanks for any help!
