OK, I checked the 2 wire grounds & they are good. I pulled the HD out & put it back in. Turned the unit on & hit the reset button. I not plays the DVD's while in motion but I still get the parking brake warning. Once I press ok, the didplay comes back on though. Is there a way to get rid of the warning all together? Also, is there a way to control what is displayed on your headrest monitors that are hooked up to your video out? I am wanting the headrests to display the DVD only, & not cut off when I go to the map screen? Is this possibe?

I can assure you that I do have the 2 wire bypass installed correctly. I have double checked this using my volt meter. This is a june 2007 model. I just took it out of the box & hooked it up. The Z2 says the update is already installed? Is there any way to overwrite the update?

I have my Z2 hooked up with the 2 wire bypass. I downloaded the iso file & burnt it to a disc as an image using nero. when I put the update disc into the Z2 it tells me that the inserted update disc is already updated? I hit the reset button & still get the parking brake crap! help!
