i just bought a new stinger spv44 battery, and after finishing my installation i checked to make sure everything on my avic was working. well, everything bit the disks were. i tried loading my disk again, but it says insert the proper disk. it worked with the same disk prior to installing the battery. Anyone no the problem or a way to fix it?

i have grounded my parking brake wire and nothing changed. what else may i have to do to bypass the security lock on the dvd and nav while moving? thanks

i have read many different post but cant seem to understand what to do. i have grounded my green wire and still is locked. what do i need to do without soldering? thanks
