I have a question...I just got my Z2 in my Lexus SC300, and had a tough time finding the VSS wire (I still don't know whether I got the correct wire or not), but the vehicle dynamics shows my speed is correct and doing what it's supposed to be doing. However, in the screen that shows "speed pulse", it always stays at "0", whether I'm moving or not. I'm assuming I don't have the correct VSS wire hooked up. Would this affect the Navtraffic from working too? My Navtraffic functions aren't lit up at all, and I know I have a subscription. Also, under XM Status, it says "no signal" and "not connected", but I looked and both cables, except the blue IP Bus cable that the instructions say are for a "CD Changer" are hooked up. Any ideas? Oh and if ANYONE knows where I can find out which wire is the VSS wire FOR SURE on a '92 Lexus SC300, PLEASE do tell! Thanks!

You have to call XM to have them re-send the signal.

I assume you have a P10 XM Radio unit. You shoulg have the Power (Yellow) and Ground (Black) hooked up (ACC (red) is not required), the IP Bus and Data Cable to the Z2 and your antenna plugged in and exposed to the sky, IP Bus cable controls the XM Radio unit and transmits audio to the Z2. The Data Cable sends the Traffic Info to the Z2. If you are getting no signal, then either the radio is not on or the antenna cannot pick up a signal.
