I have a Comand unit taken from my 1999/2000 W220 S500 It had to be replaced because it started to refuse to read navigation CD's. All other features of the unit are fully functional. The CD drive itself makes all the right noises and ejects the CD OK, it just won't read them, maybe the lens needs cleaning I don't know. It may be useful for spare parts for someone or repair, if you know what you're doing. It's marked as follows: A220 820 71 26 Comand Head Unit 2.5D-E Bosch 7 612 001 446 Model No: B0 1446 You are welcome to view the unit at any time. I'm looking for £55 delivered. I will post pictures later. PM me if you require any further info.
