20 Most Recent Pioneer DEH-P4800MP CD Player Questions & Answers

turn the unit off by pressing and holding the off button. The only thing that should be showing then is the time. Then, press and hold the function buttion. This should display the setup menu. Scroll through the menu by pressing the function button (I think). "Aux" should show up and then press up/down or left/right (not sure again). When it says Aux on or yes, turn the unit back on. Press the "source" button until you get to AUX.

There is a nice pricey part you can buy for that if you mean what I think which is having radio control on your steering wheel if so then look up your car and steering wheel controls adapter

See the first page of this manual: http://www.pioneerelectronics.com/pio/pe/images/portal/cit_11221/281256214DEHP4800MPInstallationManual.pdf

I have been installing car audio for over 40 years.A small adapter like you use to charge a phone,Doe,s not have enough amps in it to run the deck (Properly) When you crank up the vollume, The deck will cut out, You Can buy a bigger 12 Volt power supply from radio shack or the source that will power it (Properly) It should be at least 3 amp output .

If you do not have tech experience then you need to take it to a repair shop one that will give you a free estimate you more than likely need some soldering done.

While you may read over a million answers to this problem, try this one first:

With the KEY ON, POWER THE UNIT OFF, by pushing the volume button IN for 3 seconds.
After power is off and key is STILL ON, press and hold the volume button AGAIN for 3 FULL SECONDS. The elusive "Initial" settings should reappear at this point. press function to navigate the INITIAL SETTINGS to turn on AUX1 or AUX2, and even to set the clock...

To get out of INITIAL SETTINGS, simply press again for THREE SECONDS, or press "BAND" to "escape"...

I hope this helps.

you probably have to turn the aux on... usually with pioneers, u turn the unit off then hold down on either the source or the func. button until the sub menu pulls up,... scroll through until the aux option pulls up and turn it on...

Actually, TRY powering OFF the unit, and release the volume button. Then, press and hold ONLY THE VOLUME BUTTON, until the initial settings appear. Pioneer really needs to get their act together on this issue. I have read all over that MANY people have had this issue, and the website is just a repeat of their lame printed manual.

Hope this helps. In review:

From OFF, press and hold ONLY THE VOLUME BUTTON. The initial settings shall appear at this point after about three seconds...

I just read these instructions, and while trying it, I found that my FUNCTION KEY had ABSOLUTELY NO FUNCTION IN THIS.

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

Hi,
To select the AUX manually,Press function button repeatedly untill the AUX1/AUX2 appears. Press up button or down button to turn ON the AUX.
If using stereo mini plug you need to use AUX1
If using IP-BUS-RCA you need to use AUX2
Thank You
