There is so much to tell you :-) Best to use the search and start some reading.
But yeah you can turn the reminders of for the service. There might still be some crew doing the transaltion. But you don't need it. I got it done and you can't use any of the functions. Fuel consumption info and service reminder are the only things you can use and you don't need translation for them really. Best to get things replaced. Dvd, satnav, tv and Fm band expander. Good car audio shops can do it all.
P.S English stickers? Don't bother they look tacky.
