Anyone else see this!? Looks sick. Can't find any pictures except pioneers website. Looks promising though!

I saw it on the website too. It looks like it's exactly what I'm looking for. I'm surprised there's nothing decent on the market right now with good built-in bluetooth (phone and audio) and hd radio, dvd, and can run iPhone apps so I don't need to pay an arm and a leg for a navigation system. Everything out there has something wrong or missing from one of these mentioned features. Any word as to a release date?

Everything says march as release date. It looks like an all around good unit. Can't wait to get my hands on one!

I just installed the 4400 in my 2011 Prius. I had previously a AVIC F90 Premier. The 4400 doesn't have built in nav but you can add it. Boot up is almost instantaneous. It requires a relay run from the power antenna lead that grounds the parking brake as a bypass. Bluetooth audio is built in as is HD radio. It blows the factory JBL unit in the Toyota out of the water.

Good to hear. Wish they would release the 8400 soon.

Pioneer has a new video of the AVH-P8400BH on thier website. In the AppRadio (Advanced App Mode) segment, the recommeded apps icon has 15 in the red circle. It also shows things like Whodoo being used.

The one concern I have is the advanced app mode, if it's anything like the app radio it's going to be slow and buggy and a general pain to use. I returned my app radio for the AVH-P4400BH which is fantastic.

Does anyone know how to bypass the parking brake on the 8400bh? pretty sure its done with a relay but it would be nice to get a confirmation first. thanks!

The 8400 is on the street now.

I'm interested in this as well... Manual has this: Light green lead must be connected to power supply side of parking break switch. I don't know if this means it is an easy bypass or not, but I will have my AVH-P8400BH next week and definately need something to bypass it. Mainly for the app radio controls, could careless about watching videos.

Also FYI: The AVH-P8400BH does not support, from what I can tell, both AppRadio iPhone interface cable and the U220 add-on navigation module to be installed at the same time, basically it is one or the other.

Mine is on the way! And I don't think you would need the add on nav unit if you can use nav apps from your phone?

It will not be that easy, it never is. AVH units always require a relay and a wire combination to achieve the bypass. Check the bypass instructions for last years unit as it will likely be the same for this unit. If that doesn't work just give it a couple of days and someone will post a vid on YouTube that shows how to do it. Soundman is usually the first to do so.

I installed the 8400 yesterday and decided i would try the relay for the video bypass. Unfortuneately it does not work. I had the 4300 last year and the relay bypass worked just fine. I suppose pioneer has made it harder to bypass the 8400, probably due to the fact that you can now interface apps. hopefully the secret will be revealed soon!

I have the same issue. Technicaly the bypass does work but the system only checks the state of the parking brake when you switch to a video source and not as soon as you turn the unit on. I had a discussion with the guys at microbypass and this is what he said exacly:

Hello. I have confirmed that you are correct. The reason why this happens, Is in the programming software, the radio does not look at the state of the parking brake wire at turn on. If the unit is in FM, or even CD mode, and you load a dvd, The radio must be powered off then on to have the correct delay on the parking brake wire. This is a limitation of the radio. Having a longer delayed interface will not correct the problem. It will just take longer for you to see video. There is no other way to correct this, as it is written in the software of the unit.

We just recently put one of these in and can confirm that using a PAC TR7 will allow you to bypass the unit. Seems to require a double pulse on the ground wire so mode #2 which is used for the alpine bypass works fine.

This makes sense to me. My 5pin relay setup did not work, I tried multiple times.

So I pulled the ground wire and the pbrake wire from the relay. Then loaded the DVD, then tried touching the wires together, releasing, then together again... worked perfect!

So I setup a switch with those two wires, and it works great.

Switch is really simple answer that shouldn't ever stop working (as some firmware upgrades have made relays not work for other models, e.g. Appradio).

Get a 3 prong switch. Hookup the parking break wire to the lead. The ground to either of the other prongs (the prong choice will only affect if you leave it "on" or "off" to send the ground signal, this simulates the break on). The last prong is empty (just serves to break the ground signal, that is it simulates the break being off).

Yeah i guess the other way to do it is to get a switch that you can mount somewhere and manually flip it on and off when you are wanting to use the DVD function. Its kind of a pain to do it this way, but i guess you gotta do what you gotta do.

Thanks for the info though, i had been pulling my hair out trying different methods to get this to work. I cant be mad at pioneer though, this is a smart way to do it but a pain for all of us. I can see all the avhp models in the future having this same thing.

Gonna install mine later today. I will be using a PAC tr7. Hope it works.

I contacted Matt at microbypass over the weekend too. He said he found a solution like the TR7 and will be sending me a new bypass to test. I will let you guys know how it works. I should be receiving the new bypass tomorrow or Wednesday. This is what he said: I have found the same. A 6-second delay then a double pulse has worked in our demo wall without a hiccup. It requires a micro-controller to do this.

i had mine installed on Friday and had the same issue with the bypass. The install shop finally wired a switch with the parking brake bypass as a temporary fix until someone posts how to bypass correctly. Basically the radio boots up and i have a switch that I turn on every time I turn on vehicle and I can view video. Its works!

PAC tr7 works.

Hello. I have confirmed the new one from Microbypass.com works on the 8400.

What wires go where on the TR7?

I noticed since we are using the alpine hookup, it has two wires that say handbrake and footbrake input... do I use both?

- Dan

TR-7 wiring:

Red-12v

Black- ground

Green-amp turn on/remote wire

White-parking break wire (long green wire)

The rest of the wires are unused for the bypass.
