Carwings protocol

:Nissan Leaf
Carwings is the telematics system installed in the Leaf. It has four endpoints, apparently:

  1. The cellular modem in your car
  2. The data center, operated by Airbiquity
  3. The web-based Carwings interface
  4. An XML-RPC-like proxy used by the iOS and Android applications

Mobile app proxy

The mobile app proxy is located at https://nissan-na-smartphone-biz.viaaq.com and allows iOS and Android apps to interact with your car’s telematics.
There are at least two endpoints
