looks pretty neat. it's a single din unit, 40G HD (with maps on the HD), tmc, support for a BT module etc. not too bothered about dvd, bit it plays those and video too. only a 3.5" display but that's still usable, and it doesn't obtruct the aircon controls or require me to hack away at the dashboard to make a double din space. and I think it looks alright.
You can do it from the engineering menu but I've heard that the changes dont last but I could be wrong. AFAIK, you can have at least the MB ''Star'' or ''AMG'' and change the background and text colours.
All anecdotal btw, I've never dug that deep into mine even though I can access the menu, that is a whole new controvertial ''topic'' .
Portzy.
EDIT: My preference is for the built in look so to me its worthwhile, (I'd forgot about the original thread starter btw ) . The decider for me was eyesight as I needed something bigger
