well I did alot of looking and ended up going with the Z1. I am concerned with some of the nav issues but, they seem to be isoloated to only a few.

so while I am waiting for the z1 and sirius add on to show up does anyone know where the VSS wire is in a 2006 Toyota Tundra Double Cab 4x4.

Thanks.

Seems like a good group of people here and I will probably need the help.. LOL

I dont think there are many Nav issues as long as you hook up the VSS wire. I dont have mine hooked up and i still have no issues.
