Hey all,

I just bought and installed the pioneer AVH-P3200BT. My brother in law bought a no name deck from ebay that does all the same things essentially. In the no name deck's brochure it says that if you want constant video on the display to connect the brake wire (that allows only picture when ebrake is on) to the ground wire. We did that and it works fine. Could the same thing be done with the pioneer?

Thanks for any replies

 

Nope. You need to run a relay to ground. I'll find you the link, pretty simple though.

 

Here's how its hooked up with a standard relay:

85 Remote turn on wire (from deck)
86 Ground (to car)
30 Ground (to car)
87 Green (parking brake wire from deck)

 

call me stupid, but not sure what this info gives me.... thanks for your help

 

You need an automotive relay. The numbers represent the connections on the relay.

Wire it up as described and you will be able to use your 3200BT without having to engage the parking brake.

If it still ain't clear, just youtube it.

 

just get a basic a/b switch (one off setting one on setting) and take the cable that tells you to connect to the parking brake, and route it to a ground. Then you will just have to flick the switch back and forth and it will work for you. You don't need any special relay, just make sure the switch is hidden as it is illegal to have it hooked up in this manor.

 

on the pioneer you should just be able to ground the wire.


the relay is only needed for the alpine units

 

Nope. The newer versions (3200, 4200, etc) seem to have caught on.

When the unit starts up it looks for an open circuit, if the circuit is closed it will not allow the video to display.

I'm sure you know this, but for the benefit of others, the relay is hooked up to the remote power-on wire which enables the relay slightly after the head-unit starts up, thus tricking the unit into thinking the parking brake was applied.

That said, the switch method mention above will work, but personally I think the relay method is the cleaner way to go. You're splicing two more wires and don't have to mount a switch somewhere or fuss with toggling.

 

Thanks for all the info. Going to be doing it this week end

 

a lot of the older ones have to have this done as well.
