Mounted centrally, connecting to multiple vehicle data networks — requires specialist coding after replacement.

Frequently asked questions

Modern vehicles often use multiple separate data networks (for speed, security, and organisation) that don’t speak the same protocol directly — the gateway translates and routes messages between them so all systems can communicate as needed.
