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.

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.

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.
