I am having trouble with the system error popping up of "Parking Brake not being properly grounded".  I have the light green wire doubled into the ground wire itself.  I never had an issue with this in my prior car, but the car I currently have it in just keeps giving me that error.  Will a relay be needed or...

Yes. I did that and it still comes up.

I have the answer you seek, but it'll cost you $35.

Go away.

Connect your parking brake wire correctly. AVIC bypass is software only on the x000 and x100 models.

Go away.

What? OP can auction off their contributions on eBay, but no joy for me? )c:

straight grounding the parking brake wire will not work.  The radio requires you to disengage the ebrake then engage it after the radio has been powered up.  if you just ground the wire there's no way you can simulate this.  There are a few ways to get around this.  The simplest way is to just hook up a toggle switch between the ebrake wire and ground so you can flick it on and off when needed.  You can also purchase a bypass on ebay or amazon that will automatically simulate this for you.  The last way only works on the avic nex units and that's to press the bottom left corner of the screen for like 15 seconds and it enables video playback,.
