In an automotive infotainment device when I would like to integrate Alexa in order to give customer control over the device, for example: "Alexa, Play FM Radio" or "Alexa, Skip/Play Next FM station in list" or Integrating Navigation commands with Third party nvaigation softwares. I find Custom Alexa skills not appropriate or confusing to create.
How can i add custom skills like the ones mentioned above so that Alexa can be used for controlling the device. (By default Alexa is only using iHeart Radio which is Internet Radio but we need to integrate Alexa to use Device Radio)
