Re: Head Unit Replacement Confusion
In some cases you can just ground the wire to the frame to clear the parking break lock. There are lots of notches and holes that you can bolt to on the glove box frame. Works great. Some HUs need a relay you can buy at any Radio shack. The relay cycles the power on, then off to trick the HU into thinking the parking break is on. I've been told that some HUs have been made to where they actually need a switch because they have to be cycled several times to work around the relay everyone uses. I haven't actually seen any of those HUs though. Work them down one by one and see which one works. There are lots of videos that explain how to do them.
If it helps, I don't know anyone that hasn't worked around the parking lock.
