UK mode can be turned off and other 'available' features enabled. Things such as Fuel tank content display, MPH/OTG in the status line, tyre pressure loss warning, auto folding mirrors (model dependent).
All for a nice cheap MBCLUB forum rate which includes a quick test of the whole car for any problems past/present. We can also enable the phone buttons and navigation display in case you decide to add ipod/phone or comand at a later date. Saves you going to the dealer.
