Is 220d Service Menu

[giorgoXXI]

I was getting complaints from people that they couldn't hear me properly through the Bluetooth system. So I searched for a while, and found out this "secret" menu in the multimedia system to adjust the Bluetooth and a few more things. Not to sure if it has been mentioned already over here, but here is what you need to do to activate the menu:

1. Engine ON

2. Headlights off

3. Press and hold the info button down

4. While holding the info button down, move headlights from OFF to Parking lights and viceversa 3 or 4 times

5. The menu should come up

6. To exit, hold DISP for 3 secs.

Hope this helps!

PS: The menu is intended for professional techinicians, so I wouldn't touch many settings unless you know what you are doing. It probably works on all IS models.
