Connection to repeater
To connect to the repeater, you need a cable with appropriate connectors. If you connect the tripmeter with a repeater and an external device at the same time, e.g. Garmin you need to use a signal splitter.
Accessory connector
The accessory connector is used to connect a repeater, Garmin device or speed warning light.
ALWAYS use accessories available in our store. We do not recommend any other use of this connector.
