So my radio reception was good with the factory head unit.
I put in a Kenwood HU, and now my radio reception is fairly crappy -- I can get most FM stations, but they go staticy in underpasses, and the scanning station recognition is very poor; also the AM reception is completely useless.
The Kenwood support line claims that the antenna type that is embedded in the window are such that the radio circuitry is specially tuned for it, and that I'll need to install a standard antenna.
That's lame. Anybody got any ideas on this?
