    how do you make changes to the initial settings menu if the AUX does not appear in the SRC-OFF cycle through

    how to get on to aux

  • Anonymous Jan 25, 2009

    I have the Pioneer DEH-P5800MP radio.

    I bought the aux cable too and have everything installed correctly, even to power and ground.

    I cant find the aux on the radio itself.

    For some reason it just shows radio and tuner mode

    but not aux :-(

Turn unit off by holding the Source (volume knob) button until power is off.

Now, hold down the Function button (FUNC) until the unit turns on. You will now be in the Initial Settings menu, a special menu. Press the Function button (FUNC) again until you see the word AUX, press up to enable it, then press the Source (volume knob) button until you see AUX. It works now, congratulations.

You have to select the correct AUX input on the Pioneer. You cycle through the input sources with the SRC-Off button. If the AUX is not shown then you need to enable it in the initial settings menu.

    You need to plug the ipod OUTPUT into the Pioneer AUX INPUT if there is not an INPUT socket on the Pioneer then it will not work.

    The Pioneer deh-7800mp has an AUX INPUT socket. This is a Line level Socket designed to connect to the headphone socket on any music souce such as Walkman or Ipod. You will need to set the Ipod or whetever playing by it's own controls before any sound is made.

    An alternative is the Ipod adaptor lead (CD-IB100) which connects the DATA storage of the Ipod to the head unit interface and allows control of the tracks via the head unit buttons.

You definitely can wire an auxiliary input into a pioneer DEH-1400. The design of this unit is highly modular and thanks to the engineers who designed it there is an easy, straightforward way to add an aux input to the unit. The way to do it is to decouple the the AM/FM receiver stage from the volume control/Amplifier stage and inject your MP3 audio signal there. If you have experience taking things apart, know how to use a soldering iron and are good at basic electronic wiring you can do it. It does take some time but for me, it was worth it.

Look for and down load the service manual for the deh-1400. I saw it on a number of sites and at least one of them lets you D/L for free. This has a schematic and will help you understand everything described here.

There are spare (unused) line level audio inputs to the Volume control (VC) chip but I was concerned that I would have to somehow re-program or spoof the system controller to tell the VC chip that the spare is being used, so instead I just decoupled the AM/FM receiver line stage from the VC chip. This is easily done by desoldering and removing jumpers JP96 and JP100 from the circuit board. You will see the jumpers when you take the unit apart, they aren't shown on the schematic or labled on the PWB layout drawing. These jumpers connect the FM line out to the input side to C311 and C312. Once the jumpers are removed, you now have a usable stereo line level input to the VC chip that utilizes all of the audio equalization and amplification features of the unit.

So how do you select between AM/FM source and Aux. input source you ask? Well, I just took the brute force approach and wired in miniature Double Pole, Double Throw (DPDT) Switch. One position joins the FM stage to the VC chip (like the jumpers previously did) and the other position connects the Aux. input to the VC chip. A convenient space near the head unit (on my 15 year old truck) was available on my dash to mount the switch and 3.5 mm stereo input jack. (sweet).
Another way to do it is to use a 3.5mm input jack that has normally closed connections which open when the plug is inserted the Aux. jack (like GC electronics part number 30-574). (this saves a second hole in the dash and a switch that you have to flip).
I used twisted, shielded pair wiring for all wiring, (shield used for audio ground) I enlarged an existing hole on the back of the sound deck (between the heat sink and the line out jacks) to run the wiring out. I picked up audio ground at the ground jumper for the VC chip (were C307 and C309 are connected in common). The solution sounds great and works good. Just run the radio in FM mode, plug in your MP3 to the Aux. Jack and ignore the tuning display. (or tell yourself "wow, every station is getting music I like ... and commercial free too!)

Notes on Input volume level setting and input impedance: If you are plugging your mp3 player directly into the Aux. jack you will probably notice that you should adjust the volume level on the mp3 player in order to match the volume level that is fed from the AM/FM receiver to avoid a sudden change in volume level when switching between sources. If you are getting fancy (like I did) and putting a docking station into your vehicle or you just don't want someone plugging in their mp3 player at max volume and making you have to then turn the radio volume down, you should put an attenuator circuit in line with the Aux. input. The attenuator circuit that I used is a simple home made (dual for Left/Right) resistor divider network. I used the same resistor values that pioneer used in their design coming out of the AM/FM receiver stage. (2.7K Ohm for the series elements, 1.6K Ohm for the shunt elements) I used 1/4 W, 2% metal film resistors. This will provide approx. 4.3dB of attenuation and should match the line level out of your MP3 (or the earbud out at max volume setting) to the volume level sent out by the FM stage thus allowing smoother volume transition when you plug the MP3 player in. The resistors also provide some isolation/matching between the (relatively) low impedance of your MP3 output and the VC chip. (The attenuator is really optional but I like having the volume levels matched when I move between sources).
Good Luck, worked for me.

You don't have an auxillary input for that head unit.

I had the same problem, getting no output from my Ipod after connecting to the AUX port... on the cd5000 I had to press and hold the cd button thus activating the aux input.... good luck!

AUX input on Pioneer DEH P31000

There is a plug on the back called an IP-BUS. You should be able to hook the ipod directly up to that with a simple homemade adapter. I built one for mine and it works fine.

there is an interconnector to connect this unit to the aux source (CD-RB20/CD-RB10)(sold seperately).
After connecting, press SOURCE until AUX appears in the display.
Press "play" on your ipod.
i sincerely hope this answers your question.
