Ground, your video system may need to see the park brake signal on off on (or something similar) if so add a toggle switch inline with the ground wire.

On a JVC KW-V50BT I want to bypass the parking brake setup. Can I just ground the Parking brake wire in the back of the stereo?

Without actually looking at the wiring - you'll need to provide the same voltage level to this wire that it sees when the parking brake is set . This is usually tied to either +12V or -12V. So, if the radio plays when it is grounded (or -12V), you can tie it any ground in the vehicle. If it plays when it is hot (+12V), then you'll need to tie it to any +12V source. Be sure you're connecting to a VOLTAGE source, and not a data bus that is found in newer cars.

Once you do this, the radio will be fed a signal regardless of the parking brake position.

I need help my new BOSS BV9560B display Warinig please stop watch video player when I'm play DVD

It's because the pink wire (brake system) is not connected to anything. It is a safety feature to make sure that you are not watching the DVD while driving. I just installed my BV9990 today and had the same issue (before taking care of that pink wire).

Boss BV9055 Power Up Problem

12/29. I actually figured this one out myself after reading posts concerning parking brake over rides. It turns out that the Boss BV9055 will not powerup if the pink parking brake wire from the units wiring harness is not grounded. Once I grounded that pink parking brake wire the unit did power up.

Bypass parking brake wire

Boss Audio is the easiest in-dash DVD on the market to bypass; all you do is ground the ebrake wire. I recently installed 12 Boss Audio in-dash BV-7300's and did this to all of the decks problem solved. By the way I did this because they were in the back of limousines where the driver couldn't ever even see one of them while he was driving. I don't think there will be a problem, try it.
