Abstract: An interface device connects to a mobile application running on a mobile device to provide vehicle navigation assistance. The interface device includes a microphone, a location determining component, a display, a plurality of indicator lights, a short-range communications transceiver, and a controller. The controller is configured to: receive a spoken instruction or query from a user via the microphone; send data associated with the spoken instruction or query to the mobile application running on the mobile device via the short-range communications transceiver; receive navigation data based on the spoken instruction or query from the mobile application running on the mobile device via the short-range communications transceiver; determine a current position based on one or more signals received via the location determining component; and provide at least one of a symbolic output or a textual output via the display based on the navigation data and the current position.

Abstract: Techniques are provided for implementing a camera display system with selective activation of one or more associated auxiliary camera units by a navigation device in wireless communication with the auxiliary camera units. The navigation device selectively activates auxiliary camera units when video data from the auxiliary camera unit is to be displayed on the navigation device. The navigation device transmit an activation signal that may be received by an auxiliary camera unit, which may transition to an active state and begin transmitting video data captured by the video camera to the navigation device. Selective activation of an auxiliary camera unit reduces the amount of energy consumed by the auxiliary video camera unit because it is not continuously capturing and transmitting video data to the navigation device. auxiliary camera units may be activated in response to a user input or automatically in response to triggering events.
