Well after almost missing my V due to a shipping problem before my trip last week. I'd have to say this thing rocks. I do mostly highway travel to and from work. A little city driving on weekends. I leave it in A mode. I may change my options to auto mute K later on. Since I've had it ( only 2 weeks) I've only caught 1 LEO in SC going to the beach running C/O riding about a mile then turning around in circles at night. Another suprise was when I went to hardwire in my e46 M3. I opened a plastic peice on the roof and what falls out.... Hardwire kit. It was already installed by the previous owner. Just pluged it up and off I went. Pretty crazy.
