I have a Question, I want to connect my Corsa VXR steering wheel remote control, but I have three wires, one for the ground which are connected to car ground, one for the electric antena wire which turn on buttons lightning when stereo turns on, and one wire to the stereo for remote control signal, I donīt have the folder buttons, just havve this buttons:
-tune up/next track
-tune down/previous track
I think itīs possible, because I donīt need to connect anything to the ring, but when Iīve connected, just works the source button, and the other buttons works like ATT, all buttons turn on its lightning when stereo turns on, do you think I have to replace the genuine resistors with this values and all works well? Are you sure itīs +5V DC, or ground power?
Sorry for a lot of questions,
Iīm using a Pioneer AVH-P4000DVD unit.
Nice civic! I love that silver shift knob and its black boot with red threads, I[m planning to do something like that, steering, boots, doors and seats.
I really think you need all 3 wires. It's a bit strange pioneer build it this way. But that's probably to make it a bit harder for us.
Can't you use the antenna/light wire as 3th wire? and try to connect your button lights to one of the 5V DC wires? I don't know if that will work but it's worth the try!
I have found this thread searching in Google information about the wiring of pioneer car audio units. I know it is a bit old this post, but I think it is worth the try to post here my question as I see you all know what you are talking about!!
I have a pioneer unit, deh3600mp, with a jack for the wired remote in the back. My car has a stalk adaptor, so the controls are not on the steering wheel. The connector of this stalk is square, green or yellow (I am not sure), and I have an original interface from Pioneer, CARPI 034, bought specifically for my car. But it is not right!!!!! Now I would like to check the signals of the interface and those of the connector of the car, so that I can pair signals as I think it is only a problem of different design of the connector, nothing more. But I dont know how to do it.
Do any of you have any idea about this? I very much appreciate any help on this.
Where can i find similar info for Kenwood wired remote?
just wondering, im about to order all the stuff to build my own remote on a project board, but you dont need the IPbus and power connectors like you do in the original remote kits?
Or will it work just by plugging it into the 3.5 connector on the back?
Look at this wheel remote controll adapter Cir-310U
It's can use with Pioneer and any one auto.
What you say about it ?
Has anyone connected a microprocessor to the Pioneer remote input?
It could of course be done using a set of relays, switching in the appropriate resistor, but perhaps it could be done in a neater way...
A digital potentiometer was what first came to my mind, but then I thought:
If the resistor becomes part of a voltage divider inside the unit, maybe the unit is actually looking for a specific voltage, rather than a resistance. In that case, I could simply attach a D/A output from the microprocessor to the input of the Pioneer and set it to generate series of output voltages...
What do you think?
You don't need either relays or digital potentiometer.
For this purpose, you can simply use a multiplexer, such as CD4051.
By the way, because of the voltage drop on diodes(Both Tip and Ring was 3.3v and not 5v), I used ~9.5K ohm instead of 11.25K for "Folder Up/Down".
And thank you JVDE for the scheme!
