Ok, never mind - thanks for the info.
How do you find the 729B unit in general - are you pleased with it ?
It took me a long time to choose this over the Kufatec Fiscon unit & tbh I'm still not sure I made a good decision. In the end I went OEM so I could have voice activation in the car ( which I will never use ).
We have a Touran as well so I might get the Kufatec too for a side by side comparison.
