XM Poor Reception????

[robertsc]

Owned a 2011 M37 and my XM reception is poor driving through road with surrounding trees but the same route with other XM cars is perfectly clear??? I done this test with at least a total of five cars and my M37 is only one with poor XM reception in the same area. Does anyone else M's have poor XM reception? The only thing I can think is that I have window tint. Any suggestions or others experiences would be helpful. Thanks Chip from Tampa...

See my posts..... Same problems with 2012s..... Dealer is installing improved/upgraded antennas. Check with your dealership. I still lose a little on heavily tree lined streets, but a vast improvement no less...... Also, check the status of your car's battery..
