I followed the instructions for the to wire bypass for the z2. I have the Bluetooth update installed. However, the system seems to be acting strange.
Always, when the car starts I get the 'Improper parking brake wiring' message. If I am not moving I have full access. When I start driving there seems to be times when I can and cant use the menu. I am diving, so is kinda tough for me to figure out if anything else is changing,
This does seem to be different than with just the green wire grounded, I remember that if I got that message I would have to reset the system, which I don't have to do anymore.
RIght now I am going to quadruple check the ground, probably re-mount it somewhere else, and see if that makes a different, but I guess I am wondering what behavior I should be expecting.
