Thread: R251 retrofit of Comand 2.5 NTG

I will get comand online to list the ML HK wiring loom. Its easiest to start with that (so you can check all the loom colours) and move the subwoofer wiring from that into the existing HK amplifier plug

However, given this worked on the ML without amp change, I think it is worth doing the fibre-optic bypass first and seeing if that car works !!

I think the HK menu could appear if it is set to 'force audio via external amp' even if MOST bus was turned off. Certainly the menus for UCI appear if UCI is enabled but MOST not on or MOST disconnected ..

Cheers

Still waiting here...

Could you be kind and give me the part number for the fibre-optic bypass item...I forgot to write it down when I ordered it last time from MB.

Here we are: -

Comand Online Ltd :: Special Payments :: W164 ML HK loom

(they have 1 in stock I beleive)

MOST fibre joiner is A000 545 44 84

Cheers

Eek. Looking at EPC again it is probably A251 440 18 34 but I have not ordered one to be sure. EPC says "Electrical Wiring Harness, Loudspeaker, From MY09, 510+810, 511+810, 512+810 ......
