I believe that's 5G0 035 020. It's MIB1 High (MHIG), Discover Pro, 8-inch touch display 800x480 pixels.
It's too old for native CarPlay/AndroidAuto support. You can:
1. replace the main unit in the glovebox with OEM MIB2 main unit
2. add an CarPlayBox like this or similar behind the dashboard.
If you go with OEM MIB2, you will have original CarPlay/Android auto integration. But replacing the main unit requires: removing component protection from the new unit, performing coding & adaptations to match you cars equipment, patching and injecting license codes for FEC/SWaP protected features (including navigation and CarPlay/AndroidAuto), changing the USB port.
If you go with the box, you keep you original main unit, installation is plug&play. Depending on the box that you get, you can have wireless CarPlay/AndroidAuto, HDMI input, and other cool features.
Thank you. I will probably go with the carplay box. I like the idea of plug and play and I am more than happy to have a go myself.
