Hi,
I recently installed the Vaistech system into my RX400 (Works great, and pretty easy install), but still long for integrated GPS as I did not get the nav system when I purchased the vehicle. I was able to find a radio dash kit on Ebay that replaces the existing factory radio with this insert and can fit aftermarket radios up to 4 inches (Double DIN). My question is whether anyone has a schematic of the radio wiring harness to allow me to determine what each wire is for, and also if anyone has had any luck in purchasing harness adapters. I have seen several harnes adapters for Toyota's that seem like they would work, but I want to be sure. I found a wiring schematic at http://carstereohelp.net/wireharness_Lexus1.htm but it is blurry and I cannot positively make out each label.
Thanks for the help.
Mike
