Hello! Im attempting the 2 wire bypass on my z2. I burned the iso file to a cd using cyberlink biting software. When I insert the cd in the drive it says cd rom inserted but nothing happens. I pushed map and it just went to the map screen. My hardware screen indicates my ebrake wire is grounded because it says "on". I copied the file back from my disc to the computer successfully so I assume the burn was ok. Am I doing something wrong. How do I get this z2bypass file to update my unit?? Thanks
