I've had my Home Patrol for a couple days now. I had it all set up, downloaded everything, even had a favorites list. It was working just fine. I had it on this morning and it was scanning perfectly then I noticed after a few minutes it went silent and was just sitting there scanning. It won't stop on anything. Squelch is on 2 bars and miles is set at 15. I live in a large city. Location settings are fine. I can see it scrolling through the different channels but it won't stop on anything. Anybody got a clue? Thanks.
