I have bought an Eonon headunit and can't get the steering wheel controls to work. It is supposed to be plug and play, has a connector and small box which is supposed to sort out canbus, but there are 2 other wires labelled "steering wheel control 1 & 2". Anyone know what these should be connected to.

I made the mistake of buying this unit from an ebay dealer and not direct from Eonon, and the seller is not responding to my queries.

I am assuming that the steering control wires must be somewhere behind the radio. I have searched high and dry on forums and google, but no answers.

Anyone had a similar problem? Vehicle is update 3.0 diesel (2004)
