All I'm really concerned with us to play video on the rear monitor out so the kids can watch a movie in the back seat. Has anyone verified if the dual output will output video when if driving? Subscribing to hopefully find an answer.
I have read others success by simply disconnecting VSS and GPS.
This thread is the first I have heard that using carplay/AA NAV will bring the lockout back.
Installing my 4400 this weekend... we shall see.

Yes I do believe so. Update the W4400NEX to 1.01 and after reboot...
Do the AVIC "SET ON" bypass in the lower left screen that everyone is already familiar with.

worked on mine as well. this is SO FRIGGIN AWESOME!!!!!!!!!!!!!!!!!!
I don’t kno what happened, but I took my truck back to the audio guys at my local shop, and complained, Because I initially paid for the bypass, and it wasn’t working, but after they took my truck for about 20-30 minutes, and gave it back, I can watch videos and use wireless and have full capabilities while in motion.
UPDATE..... I am still able to have video in motion, but wen i use my apple navi via carplay, sometimes it run normal, and sometimes the triangle/arrow that represents me moving on the road, faces sideways and messes up my auto re-route..... anyone that was able to do the bypass have this issue?
UPDATE# 2 A few after my first update, to this text I installed the micro bypass and updated to 1.0.1, and haven’t had any issue as of yet

you just need the latest firmware which is 1.01 and then the SET ON bypass works by pressing and holding the bottom left corner for a long time. this worked for years on Pioneer head units but was not in the original firmware on the 4400NEX but was put in in firmware 1.01

Yes i found that out, i hooked up the micro bypass too, just in case, all is well vid in motion and my navi works fine.

Unfortunately, I don't own a W4400NEX to test "in vehicle". I merely have a display model to play with (as shown in my video)...but there should be no snipping or cutting of any wires or cables, all connections should be made (GPS, VSS, etc.) and VIM and MENUs are to remain operational at all times.

Hold the lower left screen (quadrant) for exactly 10 seconds.

So in summary it worked after updating to firmware 1.01?
Yes!!! Finally. Thank you so much.
As no one responded, I did the test myself, updated to 1.01 firmware, then did the "SET ON" bypass in the lower left screen and voilá!!! Video input works when car is moving. Way to go.
Thank you for posting the solution and new firmware version! I tried the fix but unfortunately it is still not allowing me to interact with Waze search features or music apps while in motion. Have not tried video while in motion. Anyone with the bypass able to use all features from Android auto/apple carplay?

I am in the same boat. I can't get Android Auto to work at all after installing an AVH-W4400NEX in my '03 WRX today.
I installed the head unit into my car, but it was getting dark so I didn't install the mic or GPS antenna yet and everything is working great so far, except for Android Auto. When I try to use it, I get, "To use Android Auto, please stop your car and check your Android phone," on the head unit. There was also another brief error about needing to connect the external GPS antenna so I guess I'll go ahead and install that too when I install the mic tomorrow. I should also mention that my phone is on Oreo, not Pie, and I think I've hear that you need Pie for wireless Android Auto and maybe the USB cable I connected to the head unit (USB port 2 on the back) was a crappy one (I tend to cycle ones that only charge, don't work with data, to my car) and I just need to use a better one?
So far, I'm hopeful since everything besides Android Auto works even though I didn't connect the e-brake wire or the speed sensor wire, and really don't want to. I even used the screen mirror to watch some Youtube videos.
So what's the point of the external GPS antenna other than to nanny you? When I get Android Auto working, will I be able to put my phone away and while running Google Maps or Waze, it'll use my phones data plan but the head unit's external GPS antenna for the GPS app on my phone somehow???
I'm in the process of installing a 4400nex in my excursion. I have a couple of questions. After doing the "set on" menu change, is the bypass still necessary? Also, with the bypass installed, will I have trouble getting my AA to pair with my phone? I have the micro bypass installed right now, and I'm getting the "please stop vehicle and look at your phone to finish blah blah blah" even when the vehicle is stopped.

I've heard that you can just ground the e-brake (no bypass needed) once you update the firmware to 1.01. Have you connected the GPS antenna? That may be necessary. Otherwise, not sure why you are stil getting that error msg.

To update, I installed the GPS antenna but I'm still getting error messages from the phone and 4400 about needing to set the brake when trying to use Android Auto. I have to use USB because it's a Galaxy S7 with Oreo, not Pie. So I ordered a micro bypass, but someone on another forum said I just need to ground the e-brake wire, no micro bypass required once I do that, so I'll try that first.
Update on my install: I pulled my head back out yesterday and realized that my remote trigger wire had pulled out of the connector. After I fixed that, everything worked. So I have the pioneer 4400nex, google pixel2xl, and microbypass installed. I have GPS antenna connected. I do not have the VSS connected. Everything is working fine. My AA works great, and wireless AA works well also. I still couldn't watch video in motion, like others I could see it until about 10mph then a warning screen would come up. So I updated the firmware on my head unit and did the "set on" input and now I can watch video at any speed. I would like to thank everyone who has posted information about these issues as it has guided me to this favorable ending to my install. Let me know if you have any questions about something I may have left out.
Worked like a charm, shout out to krankin for this tip!!
I also installed the micro-bypass (was very easy) and originally it was failing after I started moving (sometimes the parking-brake error came up).
l installed the update and pressed the screen ~10 seconds and voila works flawlessly; took less than 15 minutes from download to install.
The installed micro-bypass also opens up all possible menu items, even when moving, BT, video, etc...
So far it has worked great without errors/warnings!
Lastly, the 4400 is a great DD deck...solid response time and customization!!
Cheers and NHY!!
Worked like a charm!! Thanks! Version 1.01 with "SET ON" bypass mode..
