That should work fine. I've used a touch in a Magellan car kit (has a built in GPS antenna) tethered to an android phone providing wifi to access the map data.

Do the special mic plugged in?

AppRadio should work on USB1, adding a second phone or Ipod to USB2 will give you access to it's stored music but the other stuff like appradio and pandora is not going to work through USB2

When I added the U-220 to my AVH-4400 my single pulse bypass also stopped doing the job. Once you add the 220 you need a double pulse bypass which is the one sold for the 8400 OR add a momentary normally open button switch in the line so you can hit it once which will fix the DVD problem. Can't comment on your other problem, something is not wired correctly.

It is basically a NO or normally open switch, power comes on, it waits a bit, the switch closes then re-opens. That is the regular micro bypass, the AVH 8400 requires a double pulse so same thing - power on, wait a bit, switch closes, switch opens, switch closes, switch opens. Not sure if the 5500 needs the single or double pulse. Also, I have a 4400 which needed a single pulse bypass but then I installed the separate nav module and it needed a double pulse bypass with the navigation installed.

Yes, blue tooth streaming is included. The "Does not include" only applied to HD radio, maybe I was confusing in the way I wrote it.

Differences between the AVH-3500BHS, 4500BT, 5500BHS and 8500BHS's

3500BHS - smaller 6.1" fixed screen, includes HD radio, blue tooth including blue tooth streaming and Pandora over blue tooth. 1 rear USB port with extension cable, 2 volt pre-amp outputs

4500BT - larger 7" screen (motorized) , does not include HD radio, blue tooth including blue tooth streaming and Pandora over blue tooth. 1 rear USB port with extension cable, 4 volt pre-amp outputs

5500BHS -larger 7" screen (motorized) , does include HD radio, blue tooth including blue tooth streaming and Pandora over blue tooth. 1 rear USB port with extension cable, 4 volt pre-amp outputs

8500BHS - larger 7" screen (motorized) , does include HD radio, blue tooth including blue tooth streaming and Pandora over blue tooth. 2 rear USB ports with extension cable plus front SD card slot located behind the screen plus removable screen for anti-theft, 4 volt pre-amp outputs

My experience is with the 4400 and 8400 from 2012 and there is a difference between the two as far as USB music goes. The 8400 will write an index file to the storage device but the 4400 will not, this makes playing music over the USB input faster (MUCH) to initialize with the 8400 vs. the 4400. I believe this difference wil probably carryover to the 2013 units but I'm not sure. It makes no difference for Ipods, just for USB memory sticks or Androids if you mount them as a drive over the USM cable which doesn't work with all adnroids...

Pandora for android over blue tooth too I think?

If you are plugging in the only advantage is iphone 5 compatibility. If you are happy with you 4S for now then skip it. I like to stream from my Ipod and the update fixed the loss of meta data when apple upgrade to IOS 6. 

I can answer that, was looking at the 3500 in best buy last night and paired my phone to the display unit. With these new units there is a line in the setup screens for pandora. Two choices available - "wired" for I-Phones and either wireless or blue tooth (I think it said blue tooth) for androids. When it is set correctly and you launch Pandora on the phone the pioneer will link up with the phone and the phone display changes to something showing "Pioneer Accessory".

I successfully updated a 4400 last night and my 8400 this morning.

As far as app mode goes, according to the table on the pioneer site that is not going to work. For an iphone 5 with the lightning cableblue tooth will work, with the 30 pin adapter you pick up music playing with control and meta data but the video and all the app modes do not work on the 8400. Basic appmode but not advanced will work on a 4400. All of it works with the older 4 / 4S old touch with IOS 6...

Great! I'm a little surprised you can't do this via SD card but whatever .

The one they don't give you

The first Koolertron I bought last year had a red wire embedded in the entire length of the RCA cable. For that one I plugged the RCA in to the head unit one end and connected the red to a switched positive source at the head end. At the camera end of course I plugged in the RCA, connected the red to the positive lead on the power plug that connects to the camera and connected the power plugs negative lead to a convenient chassis ground. Then I ran a separate lead from the backup light which gives + 12 when the light is on back to the head units trigger lead.

The last two Koolertrons I got did not have the red lead embedded in the RCA so you need to run TWO leads from front to back along with the RCA lead. Same concept, RCA to the Head Unit and Camera, +12 off the back up light to the radios trigger lead, second wire to run +12 from the switched lead in the head unit harness on one end to the + lead on the power plug, ground the negative lead on the power plug to the chassis somewhere close to the camera.

Now technically, the wire off the backup light is probably available in a harness at the front of the car and you could tap it up front if you manage to locate it rather than run the lead but I prefer not to cut in to the cars main harness.

I have mine wired differently, power to the camera is on when the radio is powered, the backup light circuit is used for the trigger. This works 100% reliably, select reverse and the picture comes up all the time. Also you can turn the camera on from the headunit regardless or reverse or not if you wanted to do that for some reason.

This one works with no programming http://www.amazon.com/Parking-Override-Automatic-Pioneer-AVH-P8400BH/dp/B007QE03IM/ref=pd_cp_e_3

Your green wire problem is doing what it is supposed to do, it needs a double pulse to close the screen interlock. In other words if you wire it to the parking brake the procedure is to apply / release and apply again to get the picture to show. Micro-bypass sells a $20 bypass that works well, it is the one described as "for AVH-8400", the cheaper $10 one does not work for this unit.

I'm not an expert but I did just install the 8400 with a Koolertron backup camera in a Miata so I'll explain how I did it which worked for me .

The instructions for the camera were a little hard to understand, initially it didn't work. What wound up working is this - my video cable had an RCA plug on each end and a red wire. On the camera end I hooked the red wire on the video cable to red and the black wire from the camera was grounded. On the radio end I hooked the red wire to a switched accessory +12 source and plugged in the RCA off course. Then on the radio there is a wire for "reverse sense" which needs to be wired to something that gets +12 when the car is put in reverse, I got that by running a separate lead from the radio to the back of the car and tapping in to the lead for the backup light. Theoretically you should be able to pick this up back in the headunit area from the cars harness but it didn't work on my particular car so I ran the lead.
