after following the instructions i found on here to bypass, so i can watch dvd while driving my nav started to show me off center either to the left or right, i was wondering how i can fix this and were i could find the vss wire on a 98 nissan maxima and what color would it be thanks for helping

by the way it is the D3 model

I read that the system recognizes where you are and adjusts it to the known roads so that this should never happen. The VSS wire might help, but it seems like an antenna issue.

Yeah, the bypass won't effect the nav operation at all.
