Maybe there's something crappy about New Jersey. I mean, even more than usual. Because the complainers about Sirius reception are all from jersey.
Frankly, I have better reception with fewer dropouts in the A5 than any of the other 6 receivers I have had in the past or still have. My last car had an aftermarket antenna stuck to the roof, and it was almost as good, but not quite. The Eos has an antenna hidden under the somposite trunk lid, and it hates trees. Every receiver I've tried, including my Sportster boombox, can't get reception in the garage with the door open (the metal door overhead is an effective signal blocker)...except for the A5. This car always has rock-solid reception, even under the open garage door.
So in my experience, the Audi antenna/receiver combination is as good at getting signal as anything else I've ever had.
