I just finished installing my z110bt (no updates) and using the hack for park brake. All the wiring is correct as I had a Z3 that I replaced. At initial start, system worked normally. I turned off the truck, and when I turned it back on I get the backup camera screen and no touch control, only volume for last source (iphone). I have disconnected the park brake wire, camera, main power, everything and all combos of those. Nothing, it goes into the b/u screen almost instantly and that is it. Any Ideas? Thanks for the help

Put the car in reverse and see if it gives you your screen back.

no it did nothing, and neither did disconnecting the wires. What I did do was unplug the whole thing overnight and went out this morning, plugged it back in and now it works fine. Very bizaar. Hope it doesn't do it again as I finished installing it and what a pain to take it back out if needed. Thanks
