I seen to have a major problem.....I downloaded the 2 wire bypass on to my z2. I later found out that I needed to disconnect the temp. bypass that I was using where I used the reverse camera as my bypass. I also never connected the wires for the bypass... Now my z2 will not get pass the bootup screen...does anybody have a solution for me please

disconnect everything, reconnect it with the correct 2-wire bypass,

and go to pioneers update website to download the new update for the Z2 and install it.
