I also took mine in for service to check out the radio reception, but for the FM band. The dealer said everything was normal and found no problem. I have had very poor reception on most FM stations. I will try and take it back one more time to get it fixed. If they don't do anything again, I am going to install an FM signal amplifier and inline static filter to fight the problem. I have the Navi, and even though the radio is a 'separate' part of the Navi it is unacceptable for a $1,500 unit.
