I just installed an Audi XM control module in my 2006 A4 Cabriolet.

The reception is much more sensitive to tree canopies than my previous car, which was an Acura TL.

I have much more fading in and out while driving on tree lined roads than I did with the Acura. In fact the Acura rarely faded out under trees.

Where is the factory antenna in the cabriolet?

Is this normal, or do I have a defective XM control module?
