Alarm sensor hanging from rear view mirror...

[robsuddaby]

Hi all, per my previous post I've just bought an R53 S and collected the other day. Whilst learnign all the interior etc. I noticed this hanging down form behind the rear view mirror... seemingly an alarm sensor hanging a cable coming from the courtesy lights bit. I rolled the windows down and locked the car and if I fling my arms around a bit inside the alarm goes off but not in any obvious manner. Why is this hanging down and where the f*** should it be really??

Are the alarm sensors in the grey housing with the small vents on the roof above the rear seats? Apologies for the s*** pic, underground car park...

There is indeed a Pure aftermarket stereo with DAB and BT on it, there's an aerial stuck to the windscreen and you're all quite right, it must be the microphone for the phone system as there's nothing on the fascia plate. Thanks!!!

Can you guys confirm that the alarm sensors are in the ceiling at the back of the car? Would make sense based on location in previous cars...

Yeah that's exactly what I thought, thanks!
