I just went around the block with the old drive earlier this week long enough to test the DVD and phone menu. I'll pop it back in tonite and see if the parking brake message comes up on my way to work. Thanks so much for all the help so far. I'm feeling confident it truly is an issue with the bypass, and probably something very minor that can easily be overlooked (like you mentioned).

It wasnt the flasher method, they grounded the wires (I think the unit was made after July 06 so only option I had was grounding wires). Unfortunately I cant take my dash apart and double check what they did, but they swear everything is grounded properly and secured in the harness.

Hey guys, I'm having a hard time trying to figure out this issue... Bought a Z1 and had the install place do the 2 wire bypass about 2 years ago. Last Novemeber I decided to upgrade and get a new Z3 HDD w/ the 2009 maps. I swapped out the hard drives and the bypass kept on working. Last month I had to send my unit in to a repair shop on the east coast (not Pioneer) to have the LCD screen fixed. When I got the unit back and had it reinstalled, the bypass stopped working and now I'm getting the parking brake warning (install place swears the bypass is still intact, had it checked twice). I t
