Hi everyone
I'm a newbie on this site and hoping someone could help me out.
Just purchased a C300 with parking sensors.
As I aproach an obstacle the light work as I get close to the object but I don't hear any beeping sound .
Is there anything I should be looking at. Someone told me to wash the sensors on the bumpers but still doesn't work.

Also, when I use the Nav. I can barely hear the person talking. Is there a volume preset I should be looking for.


Ant info would be greatly appreciated.

Thanks

In order to increase the volume of the Nav. directions you need to use either the steering wheel control or the volume knob [B]when the directions are being given.
