Hi to everyone here. my car is E39 but i think is the same with the X5
My problem is that i just installed a used board monitor with TV and GPS and all kind of these.The problem is that when i go to the settings i almost cant change anything.For example.I change the language from Germany to GB and when i press the ok button it goes again to the German.One other example is that i cant set the time and the Date.I just set it and when i press the ok button it disappears and i cant even see it on the small screen in front of the wheel.
Is anyone having the same problem with me or someone that can help me.Thanks to all
