Installation with connection to CAN bus or analogue (without CAN bus)
The RL4-MBN6 can be integrated via CAN bus as well as operated in analogue mode without
CAN bus.
When integrated via CAN bus, the interface is switched on by the vehicle’s CAN-Bus and the
R-gear signal is usually recognised, too (not all vehicles).
With the MBUX with 7 inch monitor, some vehicles can display guide-lines. To avoid CAN bus
incompatibility or to comply with vehicle manufacturer policies, an analogue connection
without using the vehicle’s CAN-BUS is also possible. In this case, via +12V switch inputs, the
interface is switched on and switched to the rear-view camera input.
If connected analogue, guide-lines can’t be shown.
