Hey guys I'm having a few problems maybe some of yall can help me. I have a escort passport 8500 (red display). Latly it's acting funky. I'll be driving down the road and It's will scream full KA band then it will change to k then to x then back to KA, and there would be no cops or stores it dose this alot. It never use to do this. This is my 3rd one I've owned, the 1st just quit working, the 2nd one was all screwie in the same way. This one work perfect up intill ab out 3 months ago. If this thing keeps messing up like this I'm ganna have to pick up a V1. My warrenty from best buy is up, so it's not just like I could go exchange it. Is there anyway to fix this?
