Integration of add-on interior modules into driver user interface

1. A system comprising:

a display integrated into a vehicle;

a wireless transceiver; and

a processor, coupled to the display and transceiver, programmed to

maintain a list of wireless factory-installed in-vehicle components,

scan for add-on wireless in-vehicle components within the vehicle using the wireless transceiver,

generate a user interface listing both the factory-installed wireless in-vehicle components and the add-on wireless in-vehicle components, and

provide the listing to the display.

2. The system of claim 1 , wherein the processor is further programmed to:

receive user input to the display requesting a change in state of one of the in-vehicle components, and

utilize the wireless transceiver to update the state of the one of the in-vehicle components.

3. The system of claim 2 , wherein the change in state is one of rolling down a smart-shade in-vehicle component or rolling up a smart-shade in-vehicle component.

4. The system of claim 1 , wherein the processor is further programmed to:

receive an indication of a change in state from one of the in-vehicle components; and

update the state of the one of the in-vehicle components in the list responsive to the indication.

5. The system of claim 4 , wherein the change in the state is an automatic change based on input to the one of the in-vehicle components from a light sensor of the in-vehicle component.

6. The system of claim 4 , wherein the change in the state is in response to input received to a user interface control of the one of the in-vehicle components.

7. The system of claim 1 , wherein the display is a head unit of the vehicle, and the processor is a telematics control unit processor.

8. A method comprising:

maintaining in a storage by a processor of a vehicle an in-vehicle component listing including factory-installed components and add-on components added after a vehicle is built;

scanning, using a wireless transceiver as directed by the processor, for add-on in-vehicle components within the vehicle;

removing, by the processor, a first add-on wireless in-vehicle component from the listing responsive to failure to locate the first in-vehicle component during the scanning; and

adding, by the processor, a second add-on wireless in-vehicle component to the listing located during the scanning.

9. The method of claim 8 , further comprising:

generating a user interface listing including both the factory-installed components and the add-on components; and

providing the user interface listing to a display.

10. The method of claim 9 , where the display is a head unit of the vehicle.

11. The method of claim 9 , further comprising:

receiving user input to the display requesting a change in state of one of the in-vehicle components; and

utilizing the wireless transceiver to update the state of the one of the in-vehicle components.

12. The method of claim 11 , wherein the change in state is one of rolling down a window shade in-vehicle component or rolling up a window shade in-vehicle component.

13. The method of claim 9 , further comprising:

receiving an indication of a change in state from one of the in-vehicle components; and

updating the state of the one of the in-vehicle components in the user interface responsive to the indication.

14. The method of claim 13 , wherein the change in the state is one of: an automatic change based on input to the one of the in-vehicle components from a sensor of the in-vehicle component, or in response to input received to a user interface control of the one of the in-vehicle components.

15. A computer program product embodied in non-transitory computer readable storage having instructions for programming a processor of a vehicle in communication with a wireless transceiver to control a display, comprising instructions for:

maintaining a list of installed in-vehicle components,

scanning for current in-vehicle components within the vehicle using the wireless transceiver,

updating the list based on the scanning, and

sending, to the display, a generated user interface listing of the current in-vehicle components.

16. The computer program product of claim 15 , further comprising instructions for maintaining, in the list, identifiers of factory-installed components and add-on components added after a vehicle is built.

17. The computer program product of claim 15 , further comprising instructions for removing an add-on wireless in-vehicle component from the listing responsive to failure to locate the wireless in-vehicle component during the scanning.

18. The computer program product of claim 15 , further comprising instructions for adding an add-on wireless in-vehicle component to the listing located during the scanning.
