The parking brake wire is a ground engaged when you have the parking brake on. So just ground the wire. Make it a very solid ground or it won't work. You basically changing the grounding location from the parking brake to a different ground. When you put it on a new ground it will be active anytime. Where as with the parking brake, the wire only gets a ground when the parking brake is engaged, follow?
As far as just bypassing it flat out as in not using the wire you can't, not for viewing the screen anyway. The ground wire is a safety feature and must be grounded somewhere to view the screen.
i would suggest not ground the cable because as you know that a signal will travel the path of least resistance. you could interfer with your ecm and that is a whole different set of problems that will cost you a ton of money to fix. there is a reason for the safety features. I know it's a real pain, but the devices were designed this way so that the liabilty issues would never come back to bite them. I know this is not what you want to hear, but please rate the solution anyway.......thanks
here is what you need to do is, get a toggle switch and hook one side to a ground and the other side to the parking brake wire on the unit.
use the switch as a brake because you have to set brake for a few seconds then release and set again but keep it on this time.
you will have to do this every time you start the car.
I believe this is a safety problem to prevent distractions to the driver since this unit is installed in eye sight of the driver. Parked position is fine because the parking brake is on signifying you are stopped. Once moving it should turn off multimedia functionality. Try grounding your parking brake cable to think it is always on :)
