I just installed nav in my tahoe and two questions:
1. The VSS isn't working and I used the JP Customs kit to the green/white wire. Anyone had this happen to them, or know how to fix it?
2. The clock can't be set, is it because the gps antenna isn't installed yet? I already had the unit flashed so the radio is working.
Thnaks, Chris

you're on the wrong Green/wt. wire. I'll bet that your thermometer on the mirror is wrong too!!!

Great, I'll look again I thought their was only one green/white wire back there.
Know why the clock doesn't work?
Thanks.

the green and white wire is in the bcm and i believe there is 2 of them so u will have to test them both. also if u do a search there is some info about a gps install and it has a pic of where exactly u need to go to find the vss wire. if u still cant find it u can always go to the wheel.

Your clock wont set? Have you driven it down the open road? Out of the garage? Mine just took a while for it to set the other day when I removed the HU.

Yeah I have driven it down the road, but I don't have the gps antenna yet. Maybe that has something weird to do with it??
I did find the corrct grn/wht wire on that right though, thanks guys!

VSS still doesn't work anyone know if the gps antenna would affect that maybe?

your Nav Radio clock will not work without GPS antenna connected, as well as few other functions.
if antenna is not connected , your Nav does not know your vehicle position

Thanks for answeringthat question. Hopefully hooking up the GPS antenna will fix theVSS not woking either!!!
