Thanks, finally you know what I want. I have another original navi in my family car, the map is clear to see and the screen is big/bright enuf, friendly use, but not in X3, I felt disappointed on that. B'cos I need to look at the map sometimes, so I have difficulties on that. Now I understand BMW navi sucks, then I won't recommend ppl to use it.
