Car broken into. No car alarm, no notification on phone

Car was broken into yesterday evening in Stanmore, London area.

Thieves used a bright light to shine through the tinted windows and nicked my rucksack which had my laptop and enotebook. They also stole my body warmer.

What really confused me, this is one of the most technically advanced cars out there but as I’ve found out, the alarm doesn’t go off if windows are smashed.
