Bypass parking brake wire on Pioneer AVH head unit the easy way

[czargee]

I recently installed a Pioneer AVH-521EX double-din stereo in my 2004 GMC Yukon and found an alternative way to bypass the parking brake wire.

This seems like more work than necessary. On my Kenwood I just grounded the parking brake wire to the back of the unit. I believe that works for Pioneer units as well.

It is pretty stealthy tho--if you have teenagers that are driving age.

True, good point. I didn't think about that because there's no way in hell my kids will drive my car when they are old enough. They can buy their own $500 shitmobile.

For my Pioneer, if you simply ground the unit, you won’t be able to play the video. There would be no way to do or mimic the function of “disengaging and engaging the parking brake.” Unless I’m missing something.

I just wired in an on/off switch in the parking brake wire for my Pioneer.

From what I read (and did to my Kenwood)... grounding the parking brake wire to the back of the unit causes the unit believe the parking brake is always engaged. It allows the video to work on mine. Maybe the Pioneer has some sort of protection against this? I don't know.

Actually now that I think about it... I did this same thing to my father in law's Pioneer last year and it worked as well.
