I have the Z1 and I am unable to input addresses using the address touch screen button . The address touch button is not even highlighed. I can input addresses using the voice cammand and it works OK. I also noticed that when trying to input the check marks into the points of interest box they won't check off. Does anyone have any Idea what may be wrong?

is your system bypassed?

sounds like it thinks the car is in "drive" mode, something may not be hooked up correctly?

They did install a gadget for a bypass so I could input the address while driving. I also updated the firmware a while back. Maybe that had interfered with the gadget.

Yes, if you updated the firmware it would cause your bypass 'gadget' (light flasher) to stop working. You will need to do the 2 wire bypass (see sticky posts) or connect the parking brake wire to the parking brake per the installation instructions.
