yeah...well see whenever i get around to doing all this. just been too cold out lately and i get off work late
because GPS is inaccurate, and drops out. the speed sense wire keeps the nav system chugging along, and gets you those last 10-20 feet of accuracy. it also makes all the funky guage features work.
When I did my headrests I ran the wires under the seat frames where the recess is right about where the ear shaped bracket comes off toward the console.
That let me leave enough slack to avoid pinching them at full front or full rear or with the head rest up (yes you need slack for that)... you better get someone to move the seat while you watch the cables the first time you put them in... \\
and No, I don't want to talk about it.

sounds like you learned the hard way. yeah i figured the headrest stuff out already. just the speed sensor wire and the reverse light wire i heard is in the a pillar. anyone else knows where exactly the speed sensor wire is and what color? thanks!
i can tell you one place you can find it...
the cluster has to have a speedo wire
That would also be known as the VSS wire, and I be the instructions on installing a factory nav (avalanche forums) would include it, might even have a picture
Also the avic forums had it listed as a4 behind the cluster, according to 12volt.com it is correct.

also on avic and 12volt I learned that the back up wire is lite green at the BCM... just have to find out where hte body control module is, and look for the lt green wire.
