Can anyone tell me what the two little electrical fittings are, on top of the dashboard, one on each side underneath the windscreen. They are like small microphones; one has a red indicator light (not illuminated) and both have a wire gauze or mesh disc like a microphone or speaker cover. They "point" in towards the car, and I thought at first they were burglar alarm sensors. But the red light doesn't come on (I would expect it to blink, like an immobiliser). I have seen these on another MB I test drove (1995 vintage) so they may be MB features. But my handbook does not say anything about them. Perhaps an alarm is an optional fitting. If it is a burglar alarm, how do I switch it on?


Another possibility I thought of was that they are something to do with a mobile phone, but I don't think so because there is a small Nokia speaker in the passenger footwell, and a mike near the rear-view mirror. Why have more.

Thanks to anyone who knows!

I would have thought they were the alarm sensors (approx. 2cm long x 1cm square), other than that could they be after market speaker tweeters?

But how do you "set" them? I am assuming that the alarm is not set by locking the doors with the remote, because the red light on the right-hand sensor remains off. Also, because the car was broken into a few months ago, and the alarm evidently didn't go off.

I presume the alarm doesn't work any more. On mine I've a led near the light switch which flashes when armed.
