CAN Bus Speed Pulse Interface Navigation systems - Taximeters - Cruise Control - Fleet Management - Parking Sensors - Motability - Speed limiters CANM8-NAV is ideal for use when installing Navigation Systems, Car Audio & Entertainment, Mobile Phone Hands Free Kits, Taxi Meters and many other systems which require sensing of vehicle systems, such as speed and ignition.InstallationThe interface as standard features a mini wiring connector, which unplugs to allow easy installation. There are 2 connections to the vehicle CAN Bus wiring (CAN Hi & CAN Lo) along with a connection to a permanent, fused 12v power supply and an earth connection. Alternatively, a 'Plug & Play' connection loom is available seperately.The remaining 6 wires are conventional outputs which are generated from the CAN bus. These outputs are: 12v Pulsed Speed Signal 12V Pulsed RPM Signal 12v Ignition On 12v Reverse Selected * 12v Illumination On * 0v Hand Brake On * * Please note, some vehicle CAN systems do not support this output and so the output function may not be available to all installations.

CAN bus (for controller area network) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. CAN bus is a message-based protocol, designed specifically for automotive applications but now also used in other areas such as aerospace, maritime, industrial automation and medical equipment.
