Question about Pioneer DEH-245 CD Changer

2 Answers

Odd frequency I own a DEH-345, I think its identical to the DEH-245 model(at least the picture seems to be the same). Had a problem since day 1 - the radio could only be tuned to odd frequencies (91.7, 91.9, 92.1 etc). After I took it with me to my home country i was told that fixing that would cost a great deal and forgot about it. Recently I heard that someone with the same problem found a fix to it, on a different model(i'm guessing since he described an "audio" button mine doesn't have). I tried but it didn't work with mine. something with changing it from FM 100 to FM 50. Is there anything I can do?

Got this answer from pioneer - "This unit was designed only as a US model and the frequency will only stop on the odd numbers, ie. 91.1, 92.3, 100.3. To change this it would have to go to a service location and have the tuner changed. There is no switch to change the frequencies" If I ever had an "audio" button, the letters wore out. I dont have an audio button now. I guess thats the answer - don't buy american radios and take them back to europe. unless someone wants to post a solution that shows where is the audio button? madhat?

Hey, all you have to do is to turn off your radio and press on the audio botton until you can adjust your clock, then press again until you see "FM 100" on the display, now push the ">" botton to change it to "FM 50" and finaly another long press on the audio to wrap up.. and it's done.

DEH-P7900 BT US model. Isthere any way I could change the tuner frequency to european one. Thanks.


The DEH-P7900BT is almost identical to the DEH-P85BT sold in Europe.

This is a US model and will tune most AM/FM stations in the UK/Europe. The FM broadcast band is 87.8 to 108.0 MHz. so it will not pick up any FM stations outside this range. Also, the tuning is in odd increments (such as 96.1, 96.3, 96.5, etc.) so some stations with even frequencies will be slightly distorted, depending on the power of the signal the station generates.


I found this bit of info for you but ill keep looking and let you know what i find out.
Also have you tried it in europe to see if it does work or not let me know ok

European Wiring harness not compatible with US bought Stereo


This is not as straightforward as you may think.

You can certainly buy a generic adapter harness which will plug into the European DIN harness and then provide you with the bare wire tails to patch into. You may even find one which plugs directly into the rear of your head unit without the need for patching.

But you'll find that your head unit still won't work properly as the US uses a different FM channel range to Europe (US frequencies are odd, e.g.102.7, Euro frequencies are even e.g.102.8). The channel spacing is also different.

The radio itself cannot be converted, but you may be able to buy an external converter. It won't be cheap, and the head unit display will still always show the wrong frequencies. Channel changing may have to be done directly on the adapter and not on the head unit as I don't think that the DEH-P3000 has any way to communicate a request for a channel change to any external device and this also means that radio channel presetting may be impractical/impossible.

Considering that the DEH-P3000 is an obsolete unit and nothing special to begin with you can buy a brand new Euro-spec head unit of equivalent quality for less than the cost of adapting your unit and it will work correctly without any awkward Heath Robinson adaptations.

Sell your Pioneer back to the USA where it belongs or bin it as it's useless over here.

Pioneer 345 DEH


Intermittent faults especially one as intermittent as yours can be very difficul to trace but the first things to check are loose connections on the power supply leads at the back of the radio and if they are ok you will need to dismantle your radio and check for dry joints usually around the plug and if needed resolder these dry joints

Pioneer DEH-P690UB FM tuning problem


Pioneer have factory set your DEH-P690UB to 0.2Mhz steps to match the American FM frequency allocations. The fix is not casual as it requires complete disassembly of the head unit and repositioning of two surface mount resistors. This will void any warrantee and unless you're good at microscopic soldering could also ruin the set. I did however void my 2 year warrantee yesterday partly out of frustration and because I have the right SMT tools at work. Now my tuner CPU thinks it's in the Austrailian/Asian model DEH-P7950UB and is also compatible with UK stations. A previously hidden menu is also available where I can set either 0.1 or 0.05Mhz stepping for FM and 9 or 10KHz for AM BSM scanning. The rotary control now steps in 0.05's instead of odd 0.2's on FM Hope this helps.
