Well, after starting the car, I set the language again to English and drove off. The battery seemed to pick up energy quite well (after a 60 km drive) and starts well each time. The problem is that whenever I start the engine, the computer and head unit go back to French. On the first and second steps of the contact the display is in English. When I start the engine, the whole thing goes back to French and I have to set it to English again... On previous times, the computer and head unit had reverted to French and I set them to English and they would stay so after.
It's not a big deal for me now as I'm staying for few more days but I'm very picky about her
The head unit is the top one with Sat/Nav and TV by the way.
Any help or suggestion appreciated with thanks in advance
I miss you a lot Samarkand!
