    Clarion Steering Wheel Remote control

    Hello, i have a small problem with my Clarion DXZ 788 USB:
    I want to use a steering wheel remote control but i don't know how to control the head unit. It has a mono 3,5jack for this command.
    I know that Pioneer and Sony are based on resistive commands, but it seems that my Clarion trumpet does't.
    I've just read another thread with the same issue as mine, but it was talking about Alpine... that the HU needs some kind of 5V impulses in specific frequency.

    I know how to program a PIC, it's easy for me to write a pulse-code for the HU, but i don't know the CLARION REMOTE COMMANDS, so please help me.

    Is it on 5V pulses? If so, please tell me the commands for Vol+ / Vol- / Next track / Previous track / Next folder / Previous folder and Mute.

    Thanks in advance.

    If you have the steering wheel buttons, why not just use the OEM steering wheel remote wired interface? I believe this head unit is capable.

    Thanks for your reply.
    I have the steering wheel butons, but i don't have the interface for Clarion, and it's a little bit expensive :P That's why i want to build the interface myself.

    i dont really know how it works but i know the alpines and clarions use the same aftermarket interfaces for steering controls (seperate from sony and pio) so maybe that alpine thread is your answer. if you have someone with a oscilloscope, i think thats what you need to analyze the signal. maybe find an electronics school around and ask one of the students to figure it out. hope this helps.

    Thanks a lot man, you really made my day.
    I have an osciloscope at work, but i don't have an Alpine interface to test it; but that's ok, 'cause i'll just take the commands from "alpine thread".

    wait though. i think its a different command because if i remember right, you have to set the brand on the steering wheel interface with a switch. i was just saying it is the same type of output cuz they use the same interface, suggesting that the thred you found might have a way to test for the comands. its def worth a shot but i dont think its the exact same.

    Hmmm, anyway, i'll test it. The only problem is time; but i hope i'll be able to play a little bit with it.

    So... here we go again... with no luck.
    I've tried some Alpine digital commands but the player is not responding.
    I guess the easiest way to get this thing done is to borrow a clarion interface and check it with the osciloscope... but i don't know anybody with such a device.

    LE: I hacked the IR remote control
    I put it on the osciloscope and read two commands ("Vol up" and "Vol down")

    Just like Alpine, it has a big string of 1 and 0... all commands begin with the same code So, just like Alpine... the only difference is the effective code, but the transmission is identical.

    hey
    I always want to create a selfmade clarion remote adapter.

    Did you get the command?
    I think there are many people who would know them.
