How to install (hardwired, kept inside the vehicle)

1. Choose a power point: connect to a permanent power supply in the vehicle (9–50V). We recommend having a technician install it for a neat, safe result
2. Route the cable and mount the unit: the 1.5 m cable can be routed under the console, with the unit mounted securely inside the vehicle
3. Connect the relay (if you want engine cut-off): wire the relay into the starter circuit as shown in the manual, so you can cut the starter/engine from the app
4. Switch on: once connected to power it starts automatically. The first time, park in an open area for 5–10 minutes so it can pick up GPS and the network
