Pioneer wired remote hack

1.2 kΩ + ring  = Telephone menu (Hold = Bluetooth menu)

3,0 kΩ + ring = Answer

5.5  kΩ + ring = Hang-up (Hold = Reject incoming call)

Tested with AVH-X8500BT.

Still looking for voice control. Unfortunately not found within 0Ω-100kΩ + ring.

I'm probably going to try this in the near future with my old DEH-1500R that I'm using.

Hi, first of all thanks for sharing this, I'm about to buy a new radio and I wanted to keep the controls on the wheel.  I will try to adapt this to the controls.

I have some doubts about it: in the first picture ring is connected to sleeve, but in the schematic it seems to be connected to tip (5V both), wich is correct? And what is the purpose of the diodes?

Hello there, great job and just in time, I just bought a Pioneer Radio-CD.

Testing your values everything worked fine on DEH-1700UB.
However, I believe that by tune up you mean preset up and vice versa.

I understand it as:
tune up pressed (8kΩ) => from 96,30 will go to the next station it will find moving upward, eg 96,60.
preset up pressed (8kΩ with ring) => from FM 1-1 will go to FM 1-2.

While testing it, it works the other way around, 8kΩ without ring will go from FM 1-1 to FM 1-2.

Hello, great job and awesome schematics. I have a question (because i never studied electronics :P)  What kind of diodes should I use? would it work fine with 4 x 1N4007 or 4x 1N4148? 

Thanks, and sorry for my English

how many watts are the resistors used?

Hi there,

I would like to thanks you for this, i've just made myself a modification on my car, and now my  command are working again (the simplest one, i don't have any diode and there isn't enought space on the circuit to solder them)  so "only" 6 functions on 8 are working.

It cost me a lot of money: 5€

my unit is: Pioneer MVH-X560BT

And I confirm those values are good on it:

1,2K = source/2 sec. off
3,3k = ATT (mute)
8,2K = tune up/next track
12K = tune down/previous track
15K = volume up +
22K = volume down -

Thanks again !

Hello, JVDE

Thank  you for the great schematic. It maybe a dumb thing but I have a little bit of confusion. My Alfa's steering controlls are split in 3 cables. Two cables with electric current (4.96v)  and one ground, can you please tell me, where each cable should go in the schematic?

Thanks in advance!

hi super thread, i just started research to send commands to my deh p65bt both from my steering wheel commands witch i intend to mod for this pourpus and also to control and send command via serial from my tablet, and there is something unclear to me, the 5v on ring and shleve comes from the pioneer device or do i have to provide the voltage from a separate power supply? cant wait to start my project with arduino controled mp3 player, will update here if any one wants to try it but i need to start first and this waas bugging me in my schematic as it changes a couple of stuff, cant wait for a replay,

spider2077@gmail.com

you saved us a alot of trouble finding resistor's values. can't wait to try it on my old deh-p5900 thanks again

Hi ,

My device is MVH-X175UI.  I measured the voltage of tip and ring is 3.3V.  Also,  I tried  many value 

1.2k , 8.2k ,12k ,15k    all failed. No effect 

Would you teach me how to keep going ? Any tips ?

JVDE… 

I just wanted to thank you for this! My truck does not have sterring wheel controls, so I mounted 5 push buttons (and the necessary resitors and diodes) on to a 2x8 cm board which I mounted on the front of my center console just below my fingers when my arm is on the arm rest. [skip] [vol up] [voice] [vol dwn] [prev]

Works like a charm with my new NEX and Android Auto. While 'pause' would have been nice, I am more than please with the result.

Thanks again,

Hi,

Thanks for publishing this information, it was a precious start to replace my aging BMW Clarion radio on my motorbike with a Pioneer MVH-X370B.

After making a test rig as suggested to double check resistor values (a big 10 cm lego wheel stuck on the 100k pot' shaft makes fine tuning the resistance so much easier), on my radio, 5.5kohm flips the display between clock and frequency.

Have not tried the phone part yet, but as I don't have those functions on any available buttons on the bike for the moment, it's a moot point!

Thanks for publishing these details!

Cheers,

Daniel

Hi, i Have connected AVH-X8650BT with steering wheel control in my corolla without any adopter or resistor value... the headunit has mapping option, means it can configure input signals, my problem is that when i connect input 1 on tip on input 2 with ring... Vol+ , Vol -, FWD and Backward Work flawlessly but among source, connect call, drop and voice control only 1 work and when i change the input other way round , Source, connect call, drop and voice control work flawlessly but only 1 Work in Vol+, Vol -, Forward and backward... is there any way that all a/m control work flawlessly, any help will be apreciated... 

Hi Guys

this page is really usefull  i'm about to build a steering remote for my car and i have the x4750BT
so i'm going to be posting if everyhing is working and what kind of funtions i can find on the way


 

This whole mapping ist great. It works so well for any Pioneer or Sony Headunit. My Sony MEX-N4100BT could also map it on its own but this works really creepy and the most keys don't work. But if you set it on external everything is fine! Big thanks!

Greetings from Germany

Hello JVDE, your article is perfect and most of the functions worked in my DEH-P4980MP,  except the preset up/dwn with diodes.  Is it necessary to short sleeve with ring  ? Thanks

Hi!
My hu is an FH-X700BT on lincoln LS, the measured voltage on TIP and RING is +3.3v
I made a voltage divider to read the button if pressed and assign a task. I'm working on pcb.
1 press Mute/phone button = Answer phone
2 press Mute/phone button = hang phone
HOLD Mute/phone button = MUTE/ATT
Vol +,Vol-,next,prev,Media = Source/OFF

thanks!

Many thanks JVDE, I had to adapt your scheme and values to my new MVH-X560BT and that works perfectly.
Without your 'pioneer' initiative it could'nt be achieved.

My challenge was :
. hide this new unit,
. build a remote control from the old 'Tuner List' Facade of my Renault that I let in place after installing push-buttons & resistances,
. keep all necessary functions provided by the new Pioneer, and including phone ones as separate from audio,
. build a wheel remote for +/-/next/prev (not done yet !)

First I had to reajust the res values with DC2/DC1 giving 3.27/3.26 v.
I manage to avoid any serial resistance, but keep parallel ring diodes when necessary.
Here are the values :

( assuming D1 is the ring diode )

Audio        
        
(0K and) D1        Src/off
1K8         Mute
2K9         Display/Dimmer/Extinct
3K8         Next Track  ->
5K5         Prev Track  <-
8K3         Vol up/
12K         Vol down/
47K         Band or Escape
6K7 and D1         Preset or Folder up
10K and D1         Preset or Folder down

Phone        
        
1K2 and D1         Phone Menu/Conn.Menu
3K5 and D1         Answer
5K and D1         Hangup or Reject ( 5K7 fails ! )
3K8         EnterFct or Dial ( idem next track )
5K5         Esc or Return ( idem Previous Track )
6K7 and D1         Previous Item ( idem Folder up )
10K and D1         Next Item ( idem Folder down )

I don't assign mute function to a button : can be activated with simultaneous Display + Track(or vol).
Phone menu can also be activated by simult. Answ+Reject
Phone functions Enter-Dial/Esc/Pev Item/Next Item are simply made by double wiring on equivalent audio resistances.

So I have a convenient control from old facade with
. audio fcts on left side,
. phone fcts on right side.

And sorry, I've not found that famous 'Pause' res value.
Nor the 'List' for easy Folders navigation on Mp3 usb library.

But hey,  it's just very near as perfect.

Have a nice time JvDE, and all folks on the thread.
