Got my Z2 on Tuesday evening, read the manuals, forgot what i read and had it up and running today, despite the advice from Crutchfield. I spent two days looking for a non-existant separate amp in my 02 Solara.
The buypass works, and the screen shows the parking brake is on, heh heh. So I can do some things correctly.
However, I'd rather not string a line from the battery into the cabin, and was wondering if anyone had a suggestion on where to tap the allways on + power for the XM Nav/Traffic? Yeh, got stung with Pioneers confusing instructions too.
Newegg.com still has the Z2 for S1,200, and they're one of the approved vendors.
Thanks to everyone who has posted here, it helped the decision to buy and the install, and is appreciated!
