Can I upgrade this without too much work ?

Any help would be great !
You have to follow the whole DIY...

1- Swap the HU
2- Install the USB wire and the USB socket
3- Install the MIC with its wire
4- Recode the new HU cheating your production date
5- Recode your kombi for getting the new DONG style.

Regards.
