My new E70 has a rather interesting, or should I say very uninteresting, radio system in it. It has what appears to be 7 buttons on the controller in the console, but only the TEL, NAV, BACK, and OPTION buttons are real, the other three are nonfunctional dummies, intentionally. They don't push in at all. Despite the NAV button being functional, it appears I don't have any navigation.
There's a 6 disc changer of some kind in the glove compartment and a disc slot right under the radio as well, which leads me to believe it is some super basic CIC. A shot of the screen follows.
