    Controlling the mac mini from the vehicle`s oem player

    Hello, this is my first post so I urge you to have a little patience...
    My predicament is: I have the oem rns-e nav plus interface on my car , I don`t want to change that to a mounted lcd screen. I know I have to use a multimedia interface to add multiple sources to the oem navi system. I have found a suitable one: kufatec ima-box (manual : http://www.ima-box.de/support/manuals/ima_box_en.pdf ).This interface also adds the posibility of controlling the sources connected to it (for example a dvb-tuner or a dvd player) via an output which connects to the device`s ir reciever input. (each device is therefore controlable by means of the interface`s possibility to output the required signal ).However the interface`s output is not totaly programable, it has a fixed set of instructions (signals which may differ from make A dvd to make B dvb tuner) which it can output . So what we have is an interface which can add a source to the oem screen and let you controll that source via emulating the sources ir input.
    After reading a lot through google results none of them has given me a clear answer as to connecting this interfaces output signal to the mac mini oem ir reciever and making it work (i`m supposing here that the output from the interface does not coincide with the output signals of the apple remote).
    So given a set of command instructions (signals) from the interface how do i make the apple mac mini recognize them and let me utilise the oem screen buttons to controll aplications on mac mini.I was thinking of two solutions : hardware and software .The hardware solution is to either add an external ir reciever with programmable input capability (haven`t found one yet ,only recievers with included remote ....) or make some kind of device that would translate the output from the interface to recognizable signals to the mac mini motherboard. The software solution would be a script or program that uses the mac mini ir reciever to decode the incoming signal and translate it to equivalent keystrokes (example : pressing forward on the oem unit results in the front end software of choice plex,frontrow or whatever skipping to next song or song forward if you will).

    http://www.ima-box.de/support/manuals/ima_box_en.pdf is the link to the interfaces manual. I have found a hardware solution in the meantime but i guess its not the best solution....
    This thing will translate an incoming ir transmission to a predefined outgoing ir transmission : http://www.irtrans.de/en/shop/translator.php

    this would probably be your best shot. you will most likely have to write some sort of helper app that will run on the mac, and take those signals interpret them and then do something from there. good luck though, OEM integration can be a real pain.

    I have used this device for quite a while in my home theater and it's very reliable and the software, although simple, works fine. It can trigger events from IR commands and send others in response or it can receive commands over socket connections (the ethernet version). It can also trigger applescripts.

    I based a home theater control application on it and it's been great.

    The application is really a remote control panel generator that then creates a stand-alone application for remote control.

    I should add that there is no reason why this application could not generate a front-end of some kind, but I haven't had the time to work on it much lately.
