Cheers John, those part numbers will come in handy.
I need to drop the headlining console to try to trace the mike plug this weekend. Almost everywhere I've read it gives the impression that an '03 plate should be pre-wired - but I need to check.
I looked under the oddment tray yesterday and there was nothing but the wires are apparantly accessed by undoing the underside of the armrest so another job for the weekend.
I'll have to see of there's a simple power connector to the Nokia that I can unplug whilst getting the new one working.
BTW, how did you know that that's the part number for the ULF? Only the '21' number is on the sticker on the side of the box
Thanks again. Kev
