Hi, I appreciate that this has been mostly covered but I just want to get a couple of things straight.
I've just purchased a 2005 120d Sport with the Pro HU, I can only assume the HU is the earliest version (described elsewhere as having cheap rubber dials on the front) I haven't yet removed it to find model number but I'd be highly surpirsed to see it having BT buit in. There's no USB in the car either or MULF unit in the boot, so I'm most definitely starting from scratch here to retrofit BT and USB.
The one thing I wanted to check was the MULF-Hi can be retrofitted to the oldest Pro HU without major coding issues or wasting my money as it won't be compatible at all. Or whether my existing HU won't accept USB because it pre-dates it as being a factory fitted option.
On the basis that I can source all the relevant parts (listed elsewhere on this thread previously) at a reasonable price, can I do the retrofit without replacing the HU, because that's the one thing that I wanted to avoid?
The only thing I probably won't do myself is the coding, because that goes right over my head, so looking for somewhere in the North West (as near Wigan as possible) to code the thing, assuming I don't make a hash of the physical retrofit.
Any help/advice welcome guys, thanks
