anyone with radar detectors having problems?
 

I have a fully loaded 05 and my radar detector is the passport escort 8500. it almost constantly has a signal of x, k, or ka band that is just one bar and very faint. I'm assuming it's picking up some RF interference from my car. I put it in a 03 Tahoe and drove around and it didn't act up at all.
seems like it's picking up something that the corvette does. anyone else notice anything like this?
