RTTI Splitter: Notes

In order to guarantee the traffic warning service "Real Time Traffic Information (RTTI)", a passive antenna splitter is fitted at the IBOC control module. This enables the HF signals to be made available to the IBOC control module and the CCC. RTTI is only available in conjunction with the Professional navigation system. The CCC provides the received traffic information to the navigation system.
