Parking break bypass. No relay, No switch
 

Just installed the 4400 pioneer thinking that I could just not connect the parking break wire and think that would solve the video while in motion restriction. (I was wrong, very new to this audio scene)

So now upon searching and watching various videos about switches and relays, I came across this "ebay parking break bypass kit" claiming all you need to do is splice a few wires no relay no switch etc which is quite the opposite to what I have just read.

Here are the instructions and product:

Pioneer Parking Brake Auto Override Bypass AVH P4400BH AVHP4400BH New Models | eBay

Simple 5 Minute Installation Instructions Easy as 1, 2, 3!
1. Connect BLACK wire on module to radios black wire (radio ground wire(-))
2. Connect GREEN wire on module to radios light green wire (parking brake wire(-))
*DO NOT connect ANY WIRES to vehicles parking brake wire*
3. Connect BLUE wire on module to radios blue/white wire (remote amp turn on(+)
*will not interfere with amplifiers connected to this lead*

It appears that it is a solid-state switch which is activated by the radios remote amp output. Replaces parking brake switch instead of hacking the wiring. But I'm just going by the description and instructions so I may be way off base.

That being said, it still mimics a relay or a bypass.. I used the same type thing.. using the same wires and set-up... Mine just had a relay box that I stuffed behind the head unit, I assume yours will as well :)

This will do the same thing even though it doesnt specifically state your model.

I bought one of these for my Pioneer 2500BT. (Different model, but looks the same). Simple 3 wire splicing -- works as advertised. Well worth the $10 in my opinion.

So just literally following those "4 simple steps?

I've been using these in my installs for a few years now, I love them. So simple and saves time as well. I recommend them.

im using one on my dd since i watch dvd's often while waiting for my kids. it's a nice thing to have.

you can do the same manually using a SPST ON/OFF switch.

:iagree: and since it's technically illegal to operate the video function while driving, I prefer to use a switch.

I like the ability to be able to mess with the navigation whilst moving, along with videos for passenger viewing etc

Parking break wire to ground is what hubby did (off the adapter harness). Wire is lt green and really long. Dvd works fine without brake engaged.

You really ought to Google the radio model number for parking brake bypass, many modern aftermarkets have a secret setting for when the radios are in the store displays, buyers can watch videos without having to ground the parking wire (some have a sequence for parking brake, etc.).

you mean DEMO mode? :ugh2:

I think you mean parking break detection wire coming from receiver connected to parking brake switch ( a little module under parking break lever)

Or if I'm mistaken, then you mean to say parking break detection wire connected to black ground bypasses?

I'm not sure i see what you're saying...

Nonetheless I bought the little $10 bypass kit from ebay that uses a relay the size of a penny that needs no outside connections, i.e just connect black, green and blue wires directly to radio harness. The point of the relay to my knowledge is to delay timing just enough to trick the receiver.

Kenwood and a few others are the only ones you can still do that with, as far as alpine, pioneer and others you have to have a bypass switch or module.

Jensen and other cheaper brands have this but you are correct, higher end models do not have secret menus for video bypassing.

Mine is workign without an additional bypass harness...hubby is an aircraft mech...he wired it and it works :tup:

She has a Pioneer HU :tiphat:

Than he used a relay.

For me, the $10 was too cheap to try to do something on my own. Spliced in the 3 wires at the same time I was splicing everything else and I was done. Have not even tried it for the dvd function, but it has come in handy a few times when I needed to dial a number and wanted to use the touchscreen ( from what I read, that is another function that is locked out on the Pioneer units unless you bypass)

I bought from the guy referenced by the OP. nice guy, helpful, and his bypass worked for my appradio.

Glad to help, you see every once in awhile its good to have a thread on a topic that has been previously discussed...this little nick nack is one that hasn't been brought up in the past.

Enjoy!

Instead of making a new thread, I figured I'd just ask it here.. I'm looking to return my 4400bh and purchase the x4500bt.

The difference being is that the x4500bt is 800x480 WVGA a higher and more HD looking picture. Also has advanced app mode which increases functionality of apps and quantity of apps between receiver and phone. The only downside to the x4500bt is that It does no have HD radio built in.

Thoughts?

for me HD Radio is not really needed. with this particular stereo I use the Bluetooth audio or the USB. the only time I ever use the radio is if I'm listening to NPR which you don't need high quality sound for.

Yeah, my car is mostly driven in the middle of nowhere country town so theres only 1 HD radio station nearby so forget HD radio.

But more importantly I bought a microbypass for the 4400bh already, can I use the same one for the x4500bt?

Bypass kit 4400bh=$9.99 on ebay
Bypass kit x4500bt=$19.99 on ebay (same seller)

Are they interchangleable or does a different relay being used? hence the price difference?

Yes, the one I showed you in an earlier post will work. They are the same.

I read on another forum that new pioneers use a "double pulse" for the parking brake wire that eliminates lag time. So the traditional microbypass will not work..

Anyone care to confirm or deny this?

I would say spend the $10 to try the bypass. Unless you are ridiculously meticulous you are going to be taking the dash and deck out several times to make tweaks. JMO

I think that is correct. Parking brake on, then off, then on will allow dvd player to work. So a simple on/off relay will not work.

Read the video screen when it comes up. It tells you what to do.

You would have to time your turn on and off switch just right to get it working, where as you can just use the micro bypass and let it do the work for ya.

I ordered the $20 dollar bypass that is specific for this model vs the $10 one I already bought for the 4400bh.

I plan on doing the install of the x4500bt in a few days when it arrives and this "New" bypass that has some double pulse bypass technology..
