Pioneer Model: DEH-P8400BH, USB port goes inactive

Hello Lon Delaney,

I'm not actually seeing a question here... Nor make/model/year...

but I can easily deduce you are in wonderment how to meld these many wires... with your existing world (I suspect).

if you do NOT own your own drawings... (which I strongly recommend to anyone who is going to keep a vehicle for a while)... you can (highly likely) access some quite EXGUISITE drawings at BBB Industries web site. EULA (end user licensing agreements) need be settled (as with everything technical in todays world)... but their technical drawings & service bulletins are very well worth the exposure...

For your own sake... and any subsequent VEHICLE owners/users (or repair folks)... I would STRONGLY recommend you use
factory connector plugs and fully mimic your existing wiring where possible...

The AFTER MARKET APPLIANCE manufactures... support some makes...but (car manufacturers are deliberately EMBEDDING proprietary wiring into increasingly complex systems)...

Crutchfield supports it all...

Avail yourself of their expertise & custom equipment...
They were the ones that honestly told me my LINCOLN Navigator was a pretty ugly system... but I could indeed get a 3SIXTY3 unit to accomplish what I was after.

Good luck with yours.

CK the small inline fuse on the back of radio.

In the manual Error 23 states the USB stick is not formatted with the FAT16 or FAT32 filesystem, which is the only supported filesystems supported on the unit.

I've found that I need to have my phone on with Bluetooth enabled before the head unit powers on (i.e.starting the car). If it's already started I just pop the faceplate and snap it back in to power cycle the head unit. At that point Bluetooth always connects properly.

Press and hold the source button until the CD Receiver turns off. Press and hold the center of the volume knob top bring up the settings menu rotate the volume knob until Clear memory is displayed and then press the center of the volume knob Clear memory YES will be displayed, press the center of the volume knob to confirm. The display will change from Clearing to Cleared

The DEH 4800MP does not have a direct USB connection. To get this you need to purchase a separate adapter which plugs into the IP BUS port on the back of your head unit. It is called a CD-UB100 usb adapter. Unfortunately these are becoming harder to find for a reasonable price. You can see what they look like here and they can be purchased on ebay here. Cheers, Dan

Your stereo is set up for Ipod/Iphone using the USB port. HTC and other phone makers besides thus named in the first sentence will not work through the USB....

You must use 1 of 3 methods to connect your iPod
1. FM modulator to wirelessly broadcast on a low FM band
2. iPod 3.5mm male/male direct connect cable.
3. iPod USB connection - with Pioneer iPod adapter module.

The direct connect 3.5mm port is on the back of the unit. One plugs into the radio - one plugs into the iPod headphone port.
