Hi, i had a similar problem on my X5. The Navigation device can't be fixed. but you can buy a used one from the scrap dealers in Sharjah. They dismantle cars that have been damaged in accidents and sell the parts as used. i bought a perfect navigation device for 1500 and it works till today. hope this helps.
hi.. where is Munich Motors located and do you have telephone number for them? I need to change the spring strut on my 2006 BMW 750Li and it costs Dh 10,000 at AGMC!
