Hey guys. Just upgraded from a cobra to a v1 sn 2.879. So far I am loving this thing. Bought it on eBay with all the accessories. Got it hardwired and mounted at the top of the windshield. Really the only problem I'm having is with the programing. I have set the unit to automute K band. For some reason it will only mute in small l and not L. Other than this small annoyance I'm in love with the v1. I'm glad I found this place and have already learned some stuff from you guys.
