1. A computer-implemented method for providing navigation data to a head unit installed in a vehicle, the method comprising:
- receiving, by one or more processors, an indication of a current location and a current orientation of the vehicle;
receiving, from a network device via a first communication link, map data for generating a digital map of a geographic area including the current location;
generating, by the one or more processors, a digital map image using the map data, including orienting the digital map in accordance with the current orientation; and
providing, by the one or more processors, the digital map image to the head unit via a second communication link.

Abstract
To provide navigation data to a head unit installed in a vehicle, an indication of a current location and a current orientation of the vehicle are received. Map data for generating a digital map of a geographic area including the current location is received from a network device via a first communication link. A digital map image is generated using the map data, such that the digital map is oriented in accordance with the current orientation. The digital map image is provided to the head unit via a second communication link

13. A portable device comprising:
-
one or more processors; a first network interface to communicate with network devices via a long-range communication link; a second network interface to communicate with a head unit of a vehicle via a short-range communication link; and a non-transitory computer-readable memory storing thereon instructions that, when executed by the one or more processors, cause the portable device to; determine a current location and a current orientation of the vehicle, receive, via the long-range communication link, map data for generating a digital map of a geographic area including the current location, using the map data, generate a digital map image in accordance with the determined orientation of the vehicle, and provide the digital map image to the head unit via the short-range communication link. - View Dependent Claims (14, 15, 16)

17. A method in a computing device for providing navigation data to a head unit of a vehicle, wherein the head unit includes a display device, the method comprising:
-
receiving, by one or more processors, navigation data that specifies a sequence of steps for travelling between a source to a destination, wherein each of the steps specifies a respective maneuver at a corresponding geographic location; rendering, for each of the steps, a digital map image of a geographic area including the geographic location corresponding to the step to generate a sequence of digital map images, using the one or more processors; and providing, by the one or more processors, the sequence of digital maps to the head unit of the vehicle. - View Dependent Claims (18, 19, 20, 21, 22)
