on w4400nex .what do you do to  bypass e brake

I have the same question ...

I wired mine using my old appradio bypass .

I can watch video while sitting still and low speed .

Once I start moving like 5mph + it blacks the screen out and displays safety message .

The VSS isn't hooked up , so how is it determining speed ?

GPS antenna ?

Thanks

I have the same problem,  even though I installed the MicroBypass.  And the AVIC hold the screen to disable does not work here.

Any Help would be appreciated. 

I’m having the same issue. It works at the light and back off once the light turns green smh 

I’m having the same problem, I’m so frustrated, I purchased this unit thinking it would be an upgrade to my appradio 4. I should never had spent the money on this unit:(

Hey guys, I just took my unit out, disconnected the GPS and connected the parking brake wire to a switch that is grounded . I start the car, flip the switch on then off and can now watch my videos without my screen blacking out!! 

How did that effect ur GPS signal? 

I tried unplugging the gps antenna it did work until you lanch google maps or apple maps which uses the phones gps. Once the phone connects the same screen comes back once you reach 5+ mph. So that solution is not the answer.

Has anyone tried moving the MUTE (YEL/BLK) wire to the only other open pin location & grounding it yet?? Like the older AVIC units were.

What do you mean? What pin? And what would grounding it do?

Im having the same issue, and this really sucks, I like the wireless feature on the 4400nex but if I would of known this before hand, I would of gotten the 4200nex model, But anyway if anyone knows a work around, please share with us, Thnx

I finally got around to trying my idea....it sends the radio into "AMP ERROR" mode....so that's a no go. I put the pin back to its original location, removed all power from the unit, hooked it back up, the "AMP ERROR" was gone, & the radio went back to normal operation.

ok. I tried grounding the mute wire which drastically reduced the volume. I also tried grounding the green wire, no change. I did find a hidden developer mode screen but I could figure out the password to get in. So still no video while moving. smh

bypass - does not work on AVH-4x00NEX devices.
only for AVIC of all versions.
for 4000/4100/4200 the check was only for the parking brake.

For the AVH-4400NEX in Pioneer did a double check of PKB\SPEED

You will not succeed.
Write in Pioneer that they change the code for both the previous versions of NEX

I ended up returning my AVH-W4400NEX and getting the AVIC-W6400NEX now I have video in motion. The screen is a little smaller but definitely worth the tradeoff to be able to have video in motion. Now all is well in the world.

I am having the same issue with my AVHW4400. Did disconnecting the GPS and using a micro bypass work? I assume you have to then put phone in airplane mode.

The really old z models were bypassed by pulsing the illumination wire during boot up. Wonder if they went back to this idea. Pioneer has always incorporated a bypass. Just gotta find it.

Hi ya'll. Has anyone figure out how to circumvent this as it's frustrating?

Purchased this for wireless carplay although wanted to play a movie for my 8 year old son yet this is proving to be challenging at best!

Any help would be greatly appreciated.

I signed up to this forum for this exact problem...I hope someone figures it out soon!

Subscribing to try and get the same answer. Micro bypass didn’t work. And I am assuming the the old method of a simple disconnect switch doesn’t work as well.

I found this on ebay, has anyone tried it? It says it works on the W4400.

You can try, but I'm sure it won't work.

How'd you access the hidden developer screen/menu??
