Just checked the unit, indeed the left clip is broken. It was always a perfect fit by the way, never payed attention until you say now
If you are interested, I would be happy to let it go for 120 pounds.
It's not the bordmonitor which is English or German or whatever. Your GPS-system in the back has the languages. So if you buy a MK4 for example, than you will have to pay attention. Mostly they can be set in three languages, English is mostly one of them.
Common is English, France and German.
Some have Dutch language or Italian.
Advantage of the MK4 (BMW system) is that you can program it, change the logo and language for example.
