I couldnt find the CanBus on there either, but if you email them they'll sort you out.
Cant remember the exact price, but pretty sure it was about £70 ish.
You can wire up the 9855 with a cheap £10 ebay adapter, but it takes a bit of jiggery pokery and wont auto dim with your headlights or work with the steering controls. Racetech sell the Blapunkt CanBus which is universally compatible with all stereos and is probably the cheapest one too.
No MSN for me... I don't have the time for it anymore

It sure is a LONG wait though... feels like an eternity to me!
