Just recently my z1 started freezing up and sometimes even rebooting while driving. It also boots up a little bit slower and occasionally freezes at the pioneer splash screen. Im thinking of applying the Lock-Up and Freezing Issue firmware update, but I dont know what the consequences will be since it has the 80gb hdd and upgraded to the z3?
