Thread: trouble with old pioneer deck

You need to be sure that the deck supports aux input through IP bus. some dont. If it does than there is some way to turn it on. on my double din you turn the ignition from off to on while holding the number 7 down. then to switch to Aux you press the tape button. If you have the manual you could find out how to do it in there. I have a manual for a deh825 in my car so when i get it back from the shop i will post how to turn it on on that if it helps.

well i know i have the manual for the 625 that i have. but im not sure if it accepts the aux input signal... doh.

it obviously has p-bus, or i wouldnt be in this situation . hmmm...

if you can check your manual whenever, i would be very appreciative of any help you can give. otherwise i might be stuck buying a new radio... freeking yah!!!

press the funtion key and hold for few sec when the headunit is off then you will reach the menu where you can on the AUX mode ..

I have a Pioneer DEH-P825, and I purchased that same ipbus cable. When I attach the cable and then to an rca2mini to my ipod, i notice via the display 'effx' that its getting sound, but I'm unable to hear anything.

I dont have the manual for my HU, I tried turning the hu off, but with the key in so the hu has some power, then holding down the function button, but no menu comes up. Did someone mention they had a manual for the dehp825?


Any help would be appreciated

wow... old thread re-hash here. lucky this think emailed me to tell me someone replied to my thread... i havent been in here for ~2 years.

if i remember correctly, you have to hold down one of the buttons when you turn on the ignition. i have since replaced this radio for other reasons, but i know i had it working with the ip-bus adapter.

there are a couple options here:

1. if you have an audio menu available on the radio, see if there is an option to turn on the aux input. if so, do it, if not, read on.
2. hold down button 7 when you turn the key in the ignition. you dont need to start the car, just turn the power to on, let the radio turn on and continue holdnig the button for a few seconds (i.e. 5 seconds). if it is the correct button, the you will probably hear a beep and you will be able to select aux input using the source button.

i remember there were two different buttons to press and hold depending on what feature you wanted to turn on. one was for the cd changer input, and one was for the aux input. they were consecutive numbers when i did it...

Thanks for the quick reply, I tried your methods, but to no avail.

With HU off, holding down 7 key, key on and hold 7 key for 10 sec....nothing, no menu just a blank face but all buttons are lit. Key off, this time try function button for 10 sec....same results. Tried with radio on, cd on, md on by going through source button...still nothing. Tried again, but this time with IP bus cable disconnected, still the same unfortunate results so I came up with 2 conclusions:

The Pioneer DEH-P825 may have ip bus connector and 3 preouts, but it doesn't support AUX input control, or...

It be broken.

I've long lost the manual for this thing, since I had the HU for almost 10 years now. If anyone else this HU and working with a CDRB10 cable, please let me know what I'm doing wrong! (aside from not just going out and just forking out the clams for a new HU)

if it supports aux input for a cd changer, it will support aux input from any audio device. the only difference is that there is no control logic being sent to the aux audio device i.e. an mp3 player, a minidisc player, etc. (the radio controls the cd changer, so there is communication between the radio and the changer).

how is the MD connected to your deck? is it internal? i dont recall any rca inputs on the pioneer radios of that era.

try another preset button i.e. button 6, etc., or you may have to hold down function or audio... or some other button. trial and error sucks, but it might be the only way here. (dont you hate losing the manual)

also, having the cable connected or disconnected will not affect the ability to switch the aux input on or off...

i know that on later models, there is an option in the menu to turn the aux input on and off, so that may be the case on the 825 since it was the high end cd player at that time. search the menus and see if that option is available.

one thing to note, if you can get the radio to display the cd changer connection or controls, etc, then you should be able set up the aux input as well... just getting the cd changer controls displayed will not solve this problem as the pioneer decks typically use the cd changer and aux input as separate sources. that is why you can buy the cdrb20 and have both items connected at the same time...

if nothing i have mentioned works, then i am out of ideas (for now)...

Right on man, Let's hear it for Trial and Error!

I got it to work, but I don't know how, honestly. I never got any kind of menu or any kind of confirmation beep when holding down buttons. I did have a cd in at the time, so I ejected it, I was thinking it wasn't allowing it to look for any other source than a type of cd (thing was made in 96, don't think there were any portable players around at the time, aside the minidisc or walkman).
I noticed that it wouldn't let me cycle through any sources other than radio or 'off', then I put the cd back in and now I was allowed to cycle through cd, radio...and what's this....AUX. I plugged the ip cable back in, plugged in my ipod and audio was reborn again through the AUX source.

I am clueless as to how it was done, but I'm rock'n now

Thanks for all your help!
