I bought a used Volvo VN with Vorad. the beeping made me crazy until I tried to make a right hand lane change and when i put on the turn signal the vorad beeped the "tripe beep". Looked again in the blind spot mirror off the end of the hood and there she was...a little Cavelier just waiting to be made into hamburger. Needless to say I didn't make the move and haven't cursed at the beeing since. I have used a rear camera and love it but i would get too confused with all the images coming at me from other cameras.
