I didn't go for the Nav Pro either. With all the mobile devices capable of GPS for a minimal amount, why paying HKD60K (mine's 100% tax) for a larger mon?
Besides, it doesn't really add resell value to your car anyway. And BMW charges you for updating maps after the 1st year. I think another HKD1K+ each year, for a big 2 updates a year.......
PS. For an additional HKD9K, I can have the Samsung C9000 55" LED 3D TV in my living room....... I guess I can live with a 7" mon when I am driving
