Hello,

On that topic of the newest/updated alarm siren - I see Mercedes Part #A 219 820 32 26 based on previous postings related to this topic. Is this in fact that most updated siren available or should I be looking for a different part number. If so, can someone provide such.

As a note, I realize that the newer sirens have studs requiring a metric washer and nut.

Thank you in advance!
