In the interests of continual improvement (MB agenda?), after 6 months of ownership, I thought I'd put down a list of suggestions - not complaints or a whinge, just suggestions for improvement. So here's my list, and feel free to add to it, I'd be interested in others' thoughts.
1- dimable Command screen (as above). For me this is actually a safety concern as it really distracts me when driving at night for some reason.
2- the positioning of the warning on the Command screen when reversing. It blocks the vision right where you want it. All that has to be done is position it at the bottom of the screen, or get rid of it altogether after a second or so.
3- the dreaded key start. I am going to whinge about this one. Its stupid. Make it keyless start, or put it in a more easily accessible place, or at least make it like the VW style where just insert it and push, no having to turn the key. I'm tired of fumbling around with this silly and unnecessary design.
4- while I've sort of got used to the gear shift being where the wipers etc should be, I much prefer it back in the centre console (like the A45)
5-a bigger sub for the HK system
6- remote control of the windows from the key fob as standard, and one that works from a reasonable distance(take another tip from VW boys)
7- allow Stop Start to default to off
8- have a forth Mode: Eco, Sport, Manual and Normal (where Normal is just that, not laboring around at 1100rpm all time, but rather around 2000 would be nice.
That's about it. Not much really, just a few tweaks would make it damn near perfect (although another 30-40 kw for the 250 would be very nice

, and I'm sure could be done with a simple re-map)
