Hi guys, just got my unit installed yesterday. I have the VSS hooked up as well, however, it seems that when i'm stopped at a light intersection, the D3 still believes i'm travelling in the same direction prior to stopping for the light. GPS signal is good, and i have the vss hooked up (my speed pulse goes up from 3-5 when i accelerate).

I did however, have the wrong wire tapped initially for the vss, but i've corrected that mistake already. Would that have caused my unit to function improperly due to stored memory in the unit prior to the correct vss install?

Thanks,

Try resetting the learning status. Then give the avic some time to relearn the proper vss signal and you should be just fine.
