It seems a bit stupid that it is enabled on the X3 with bus nav and not on the 3 series bus nav. I asked the dealer about this feature when purchasing the car and he could not give me a proper reason as to why the 3 series doesn't have it. I think it would be quite handy to have. My friend has a 2012 Mercedes C250 and the traffic info is quite useful on the Sat nav.
