Abstract:
1. A method for operating a navigation system for a motor vehicle having an offboard data memory, spatially separated from the motor vehicle, having data packets for transmission to the motor vehicle via a communication connection having a bandwidth, divided by region, of visual map information and a display arranged in the motor vehicle, comprising: selecting at least one of (a) data packets provided for transmission to the motor vehicle or (b) a sequence of the data packets, the selecting occurring as a function of at least one of (a) a resolution of the display, (b) at least one of (i) a chosen or (ii) an available resolution of data, (c) a location of the motor vehicle, (d) an assumed route of the motor vehicle, or (e) the bandwidth of the communication connection provided for the transmission; transmitting the selected data packets to the motor vehicle; transmitting, in response to user request for the bandwidth of the communication connection, expected values of the bandwidth of the communication connection along the assumed route of the motor vehicle, wherein if the expected values of the bandwidth are below a threshold value, the resolution of the display is reduced; and representing visual map information of the data packets transmitted to the motor vehicle by the display.
