Linked, not just fitted side by side
Fit the Storm and the S5-VTS as this package and we link the two together at the fitting stage: if the Storm notices an attempt on the ignition without the tag, the code or the app, the S5-VTS's control centre already knows about it as well, and will call you. That link is not a feature either product carries on its own out of the box, and it is not something you get by simply buying both separately.
