I am mostly finished installing my AVH-X3500BHS. I built a parking brake bypass from an automotive relay. I used this video as a reference.

I have it all powered up but the bypass only seems to work some of the time. It worked the first couple times I powered up the head unit. Last night I couldn't get it to play video at all. Does anyone know if Pioneer has made any changes to their 2013 lineup?

Pioneer is making it harder and harder to bypass the parking break I see.
When I bypassed my 930bt I didn't have to have the toggle switch or relay.

I would try using a toggle switch instead of the relay and see if that helps. Because the grounding time maybe to quick with the relay.
I assume you already checked the obvious, bad connections, damaged wires, and checked your ground?

The relay technique hasn't worked well since the 2012 line of HUs. What you need is either a trigger module (PAC TR7) or a Microbypass (got mine on Amazon). Problem is that the HU has to see the PB as on then off then on again and the relay technique doesn't do that with a time delay.

Pioneer is really starting to get on my nerves...

Can't really blame Pioneer. Has more to do with American laws and what Pioneer has chosen to do to comply with them.

I guess if you want to take Pioneer's side :/

Lol I don't take sides, just play Devil's Advocate.

I do, however, think it's ridiculous WHAT Pioneer locks to the PB being on. Like inputs to navigation apps. Do they not know that Americans actually drive with passengers who are perfectly capable of handlin the task?

The parking break issue is just annoying and no matter what they do to try and force people into using it, people are going to find a work-a-round.
So makeing it a pain in the butt is a **** move on their part.

My 2 cents. >.< lol

Hence why I just bit the bullet and got the Microbypass. Same stuff they use at the local CA shops to demo all the features, installs easy, and hasn't failed me yet.

Glad it's working for ya.
If the ground needs a delay I would go the cheapest route possible and have the two exposed wires in my glovebox and connect them as needed to have a ground delay.

Lol then people would think you're hotwiring a car. That could look kinda cool.

Back OT, though, I think your best bet OP would be to get the trigger module. That way if you upgrade or Pioneer updates their timing for the relay, you can do it on the fly rather than have to buy something else to make it work.

Agreed, I also bought the micro bypass. I think it was $20, shipping was fast, install is easy. Cant go wrong.

Microbypass it is then. I'll get one on order. Unless, does anyone know how they are built?

It's just a IC chip with preprogrammed time delays and electronic switches. Three wires: one for 12v, one for remote, one for PB signal

The video recommended earlier in this thread is the most lucid of the ones I viewed. A few tips that I didn't see on any of the videos or forums:

My Head unit setup: Pioneer AVH-X3500BHS w/ siriusxm and stock speakers. No ext. amp.

To complete this relay bypass task you are only going to be using the Remote, Parking Break, and Ground wires from the Pioneer's harness. If you are also using a Crutchfield supplied PAC or similar intermediate harness you still must connect the GND to the PAC (or OEM) harness. But, you do not need to include the REM and PB wires from the PAC or intermediate harness in your splicing.
You can tape those two wires off.

A tip on grounding requirements: A quick call to Crutchfield tech support yielded this interesting tidbit that they(or PAC) left out of the instructions:
Most likely your auto's OEM harness is already grounded. And the PAC harness GND wire matches up to that OEM harness. No need to run another GND wire to the sub-dash. I had already run a secondary GND; no harm in having an extra GND.

Some things to consider about my suggestions:
I had to alter the suggested relay wiring in the video to get the relay to trigger.
here are the pinouts that worked for me: (if this suggestion fails, try the alternative suggested in the video)
85 & 87 = Gnd
86 = REM
30 = PB

Parts required**:
*1 ea. 12V 30-40 amp relay (Recommended: 12V 40Amp Tyco/bosch SPDT 4-pin relay for sound/security systems. You want at least 30 Amp--these relays get real hot if they are rated less than 30Amp)
*a 10pk of 18-22 gauge Audio Female Disconnects connectors/lugs sized to fit the relay (my relay required 1/4" lugs).
* crimper, electrical tape, and stripper tool(s)
**all these items are available at most auto parts stores.

Follow the instructions in the video and watch it through to the end. He passes on some good info.
My install works, but...every once in a while the relay doesn't trigger quickly enough. so, I have to switch to the radio or sirius and then back to "Disk" or cycle the unit in order to get the relay to trigger at nearly the same instant that the "format read' occurs.
Play with it; you'll eventually get it to work.

Hope this helps someone.
