remove the toggle switch and pray you didnt do damage to your delicate stereo system

This can be done with a toggle switch or a relay.
**Toggle** Connect one side of a toggle switch to a ground and the other to the light green wire on the unit (parking brake input). Once the vehicle is started, just flip the toggle and apply ground. Taa-daaah.

**Relay** (see image)** This will bypass the parking brake automatically every time.

This what you do. Connect the video wire to a power suppy and install a switch in the power wire. When you put the DVD in and the warning comes up, turn the switch on then off. This will allow you to watch the DVD without the park brake being applied.

CONNECT A SWITHC TO THE PARKING BRAKE WIRE ONE OF THE PINS FROM THE SWITCH TO GROUND AND THE OTHER SIDE TO THE PARKING BRAKE WIRE.

Pioneer recommends Pioneer ND-BC2, but you should be able to use any with a descent viewing angle and RCA connections.

ground the wire to a hot (ie power comes to the wire) switch in your dash, like a rear window defroster or seat heater. turn the switch on then off and it will trick the system into thinking you activated the parking brake.

Here is a diagram...

You probably need to get the handbrake switch wire properly attached to the handbrake switch. Some people have also used a toggle switch or something and run the handbrake switch wire to that and the wire from the handbrake switch to a ground on the vehicle, then you just have to flick the switch off and on EVERYTIME you start the car to do the bypass.

Though what I'd really suggest just getting a 4 pin relay and do a bypass. You can also use a 5 pin relay and do it, just don't use the 87a pin. Another clean way to do it would be getting a PTR 7 but this costs a bit more and needs to be programmed. This should allow you to look at DVD's with vehicle moving or not.

Kali Mera, Ti Kanis?

I have been looking in to this, but there does not seem to be a hack available.
