XM Satellite Reception Problem
 

I have a 2010 TL. First car I've owned with built in XM radio. My previous 4 cars I've run a Sirius Starmate unit suctioned to the glass. Magnet antenna stuck to the roof.

I have to say; the reception in this TL is terrible. The XM radio cuts out a few times every single minute I'm driving, unless I'm going 55 down the highway with a perfectly clear view of the sky.

With my previous setup, it got amazing reception.

What is going on here??

do u have tints on your car? if so its possible that its a metallic tint which might cause some interference

The antenna is on the roof so tints would not be the issue.
