I have been looking at the Pioneer Avic-Z1 or Z2. I know the newest model out is the Z2 but they don't have a bipass for it yet, so that is way I'm looking at the Z1 also. There is a great forum about the AVIC units called AVIC411.com check it out there is a lot of info about the units there. The sad part is I haven't even picked up my LS yet, I put a deposit down on it, but still about two week from being able to pick it up.
Well looks like I stand corrected, I guess I missed the Z2 bypass some were along the line, I'll have to look into that then because I would rather have the newer model.
As far as like my LS I can't wait. I fell in love with the car the first time I drove one in 2001 while I was contracted to Ford. Now that I can finally afford one I'm so geeked.
