Cheers, I've got the fuse tap for the switched ignition to wire into the adaptor so should be OK with that.
No Canbus, it's a Kenwood DPX-7000DAB, standard ISO connections, have also bought a dual adaptor for the aerial so just need to attach that to the Blue/White wire from the stereo harness to and should be all sorted.
It's got a Dension Gateway 100 providing a line in and iPod in and there's a Parrot Bluetooth hooked in as well so hoping the mic for that works with the Kenwood to save messing in the lining. Just going to have to put the DAB antenna somewhere.
But if I'm not happy with it I'll be coming to you for an updated Canbus module :)
