X3: Navi, Phone and Setup no longer selectable

[cma410]

Dear all,

After having troubles with the Airbag control module this has been replaced by my dealer and the car's bus has been reinitialized accordingly. The repair has been covered by my extended warranty package (being called BMW Paket Care here in Austria).

Since then I can no longer select "GPS Navigation" "Phone" and "Setup" in the menu. As I have "pimped" my Navi using a modified copy of the original software CD to display an alternative startup-screen und use a modified map-DVD with speed camera POIs my dealer insists to blame this update (being in place for 2 years without troubles now !) for the problem and refuses to repair/change the Navigation computer.

Re-applying the unmodified original Software to the device did not change anything. Does anybody have an idea what the root cause of the problem could be ???

Thank you
Christoph

Sounds like we had the same problem. The X3 has an issue durring heavy rain that cause water to enter into the compartment where the Bluetooth/voice/handsfree function is located. All of the electronic for these funtions are housed in a metal box that is about the size of a brick, but with only half the thickness. Over time the moisture cause some internal corrosion which ultimately causes the unit to fail completely. Oh, and did I mention that it is very expensive to replace this magic box? Last time I checked it was $1700 new and the used units that I found were still going for well over $900
