VAG CD Changer Simulator - FAQ

Contents:

Is there a plan to implement other CDC protocols ?
Evaluating such protocols is very time expensive, therefore there are currently no activities in this.


Is there a possibility to display text characters on the radio instead of CD#/track# ?
No, because the Panasonic protocol does only permit the data transfer of numbers and some special characters (e.g. '=', '>' etc.).


Is it possible to display title data from the Archos on the radio ?
No, because:


Why there are only few Archos remote control commands ?
Because the original Archos and the Rockbox firmware currently are only supporting the described commands.
Enhancing the functionalities of the remote controls serial commands implies modifications in the firmware.


Where can I download the source code ?
To be honest:


Why there is no box and no cables coming with the simulator ?
I don't know where exactly the simulator will be installed in your car. There are cars with enough space behind the radio to install the simulator, other cars don't have enough space.
If the simulator would be mounted in a box by default, it could happen, that the simulator can not be installed just because the box would be maybe too big.

Because of the same reason it comes also without cables. The cables should be as short as possible. Because I don't know the place of the installation, I also don't know the length of the cables.
Another reason is, that I eventually don't know the necessary connector on the radio side.



Do I need a case for the simulator ?
There are no reasons against that, if there is enough space.
Another alternative is, to pack the board into a heat shrinkable tube, that also covers and insulates the connectors.

Attention:
The simulator versions with 9V supply do have a heat sink mounted. This normally doesn't get too warm.
Nevertheless there should be made a hole into the box, that shouldn't be too small to have enough air circulation.
If the board is protected with a heat shrinkable tube, the tube should be cutted to have a hole where the heat sink passes through (the heat sink is not insulated against the part, so there is risk of short cuts, if it gets in contact with other metal parts).



What do I have to take care about with the wiring and the cables ?


How can I find out, which HW and SW version I have ?
According to the HW, there are some views, that should enable you to find out the HW version (eventuelly by comparing them to your board).
In all other cases (includes also the SW version), please don't hesitate to ask me.


Why the simulator with Archos remote control is sometimes recognised only after 2x pressing the 'CD' key on my MCD ?
Following situation: In both cases it might happen, that the MCD is displaying 'NO DISC' first and the is activating the radio mode.
If you then press the 'CD' key a 2nd time, the simulator is accepted.

Explanation:
A 100% recognition of the simulator would not be the problem, but then one of the 'CD1'-'CD6' keys would be w/o function.
To have all CD keys available, I decided to accept that little flaw.
After pressing the 'CD' key a 2nd time, the simulator is always recognised, that means it never ends up in a situation where the simulator isn't recognised anymore at all.



Is it possible to remote control all Archos models with the simulator ?
Unfortunately I'm not able to answer this 100%.
I'm actualising all working combinations of simulator/radio/Archos in this list.

If a Archos model should not be listed there, maybe the following hint helps:
The simulator is using the HW and SW interface of the Jukebox Studio/Recorder models.
That means, if it is possible to remote control a specific Archos model with the original Archos remote control for Jukebox Studio Players (please check this directly with Archos), then the simulator will work too.

This behaviour is only occuring with simulators with remote control and MCD.



What if my radio is not listed at all in the list of working radios ?
I'm actualising all working combinations of simulator/radio/Archos in this list.

If a specific radio is not listed there, then it never was tried to operate it with my simulator.
If it will work together with my simulator has to be clarified individually.
