In the mornings and only in the mornings my nav system does not work properly. After i have drove around a little it'll work fine but in the mornings the speed pulse doesn't pick up (its off and on) and the installation position says excessive vibration. Any ideas? I have a feeling there is just some loose wires. What do you think?

Is it mounted firmly? It should work fine without any VSS, so unless the wrong wire is tapped and its getting incorrect VSS information, its probably something else

Could be that crappy connector too. Seen that not bite into the wire properly more times than I care to count.

hmmm had it pro installed but ya know how that goes....They said they plugged it all up....but then i had to go back and do the bypass. I'm thinking i mite have pulled the wire a lil loose or something. But the unit is very fine don't know why its saying that excessive vibration shit

ok well i'm still having issues with the stupid thing...But the freaky thing it only says it sometime and it goes way....I pulled out the unit again this weekend and all the wires are still there. I also tried it w/o the vss wire and it wouldn't work...do i have to reset it if i do that?
