The CAN-Bus adapter that come with the HU is for the steering wheel controls only.

The Resler interface (in conjunction with the iBus app) gives you access to all the On-Board Computer functions, MPG, setting the clock etc. - and MUCH more.

The Resler interface plugs into the USB socket on the HU and then is wired into the i-bus cabling at a convenient location.
