Hi AndreD,
Do you have any information as to whether the Audi TT MK2 (2008) uses resistive controls? I believe the Audi TT steering wheel controls broadcast on a dual wire CAN bus but I'm not sure if this means it's resistive or not??
I have already sourced myself a SWI-CAN which will connect to a SWI-X to then send my Infill G4 CarPC infrared signals to control the unit from the steering wheel controls. Although I know this will work, I don't like the Infrared solution and would prefer a hardwired solution like your CarButtons. The only way to program the SWI-X is with the infrared remote controller that came with the G4. I've already come across a feature I want to use one of the steering wheel buttons for but can't due to the feature not being available on the remote and therefore can't be programmed into the SWI-X to transmit the command to the Infill G4.
If your CarButtons controller will not work directly from the Audi TT steering wheel controls, perhaps it will connect to the SWI-CAN interface which interprets the CAN bus messages from the steering wheel controls and converts them to an analogue output which could potentially connect to your CarButtons controller?
The SWI-CAN & SWI-X are sourced from Pac Audio

Just a bit of info on the controls - Identical layout on either side of the steering wheel...
On the Left side of the steering wheel, there is a wheel track selection control for next and previous track which also depresses to fast forward current track. There is also another button next to the track selection which is currently used for input selection.
On the Right side of the steering wheel, there is a wheel volume control for volume up and down which also depresses. There is also another button next to the volume control which is intended for activating voice dialling.
Do you think it will be possible to use all the above controls (8 in total) through your CarButtons controller?
Let me know what your thoughts are and if you think your device will connect directly or perhaps through the SWI-CAN device.
Thanks,
Vigil.
