Volkswagen Media Device Interface (MDI) Retrofit

mdi_5n0057342Volkswagen have released a kit for retrofitting that is designed for mounting behind the dash and is a much more compact size then the original MDI that was designed for replacing a cd changer. The kit is around 40% cheaper but doesn’t include the USB cable as the previous kit did. This kit may not work on RNS 510’s built prior to February 1 2008, other information has this unit only working with B variants of the RNS 510. The firmware 1100 upgrades the unit to a B version so this should work with all units.

The Media Device Interface (MDI) offers support for USB devices (memory sticks and hard drives), iPod integration and Aux In along with displaying ID3 tags over the CANbus to the MFD and the RCD310, RCD510 and RNS510 headunit. The unit is available for the Passat which mounts in the glovebox and the Golf which mounts in the centre console replacing the 6 stacker cd changer. It is possible to mount the unit elsewhere in the car.

UPDATE: Volkswagen have released a retrofit kit that comes without the additional trim for the cd changer mounting and is designed for mounting behind the dash. See here for further information.
