Please help. I'm new to this forum and love all the info on it.

I have my Z1 installed with a TR-7 module for the bypass, and I updated the firmware to stop the freezing. Now I'm locked out the nav and dvd functions even if I engage the e-brake. The Z1 says off of the e-brake no matter what I do. How do I fix this?

Check here for the "new' unlock:

Fixed it! Did the bluetooth update, took out the TR-7, did the two wire bypass and hooked up the illumination wire. All better now, totally unlock and working great. Thanks for you help.
