This is a bad joke! The m3 has the nav with a single cd behind it but the x5 doesn't ?

The x5's:



BMW On-Board Navigation System with Cassette Player
On-board DVD-based navigation system, including 8-function on-board computer (not available with in-dash CD player; requires Premium Package)

The m3's

BMW On-Board Navigation System
On-board navigation system (available with in-dash CD player)
