Built-in vs aftermarket car tracking: what the factory system misses

May 21, 2026

More new cars ship with some form of connected tracking built in, and it raises a fair question: if the factory already put a system in, why add an aftermarket one? The honest answer is that built-in telematics and a dedicated aftermarket tracker are not the same product, even when both can show a location on a map. Here is what the factory system does, and what it leaves on the table.

What built-in telematics does well

Factory systems like OnStar and the connected-services apps from most major automakers are genuinely useful. The hardware is already installed and hidden, there is nothing for you to fit, and many can show the car’s location, lock or unlock the doors, and in some cases flag if the car is moved. Some tie into stolen vehicle assistance that works with police. For a lot of owners it is a real convenience and a real head start over having nothing at all.

So this is not a system to dismiss. If your car came with connected services and you have them switched on, you are better off than an owner with no tracking. Give the factory that.

Where built-in tracking falls short

The limits show up exactly when a theft happens. A few to be clear about:

Where an aftermarket monitored tracker fits

An independent, monitored aftermarket tracker is built around one job: getting your specific car back, no matter the brand, and stopping the theft where it can.

With ScorpionTrack, your vehicle reports to our Secure Operating Center 24 hours a day. If it moves when it should not, our team sees it, contacts you to confirm, and coordinates recovery with law enforcement. We contact you, you do not notify us. That is a monitored recovery service, not a locate-only app you are expected to watch. It is insurance approved, it moves with you if you change cars, and it does not switch off because a manufacturer trial expired.

The layered answer

Keep the factory system on if you have it, and add what it cannot do:

Every tier is insurance approved and British engineered, protecting vehicles since 1973.

The bottom line

Built-in telematics is a helpful convenience feature that happens to include location. An aftermarket monitored tracker is a dedicated recovery service that answers to you, not to an automaker’s subscription calendar. If getting the car back matters, do not rely on a trial that quietly lapsed. Compare the tiers on our products page, or get in touch to arrange professional fitting.
