All in and working fine, very happy. Quite easy to install and sound quality is actually better then I expected!

This youtube video helped a fair bit;

It is of an Icelink install into a US Accord. The only differences with ours is the shift knob removal and the connection for the unit is actually on the underside of the head unit so there's no need for the mirror. I decided to place mine in the glovebox and easily routed the cable through the right hand side. Very easy, no need to cut or drill anything. I didn't worry about disconnecting the battery either. Whole install took approx 20 minutes.

The only problem I came across with the unit was that it didn't like my Sandisk USB drive. I think it might have had something to do with the built in security software on the drive, who knows...
