A friend gave me a Whistler 945 wideband 2.6. It looks pretty old-school and theres not much about it on the internet. I havent mounted it yet, but so far anytime I move it, It goes off and gets pretty annoying. Will it still do this when mounted and stable. Theres a mute button on it but it doesnt seem to be muting very well. It has VG-2 and city options on it. I'm new to radar detectors but Im starting to do some reasearch as I write this. Any advice appreciated.
