For anyone who has 3.851 and thinks your unit could be bad send it in asap. today I was driving to the mall with my friend behind me in his audi running his original 8500 and I notice he has slowed way down. about a minute later a cop coming in the opposite direction comes driving by. we got to talking about it and he said how come you never slowed down and I told him I never got an alert.
this is pathetic and I'm pretty pissed at V1.
