As a general rule, when you choose to have the young punks at Circuit City or Best Buy install your stuff, you are taking a serious chance that they will screw SOMETHING up.
If it were me, I would DEMAND the VSS wire be connected free of charge because it is part of the Navi system.
I use BB and CC only to buy stuff - NEVER, EVER to install stuff!
And yet you're pmming one of those punks asking install questions.....
Oohhh, I knew that was coming ![]()
