I have an Android-based head unit. It gets an internet connection from mobile data via Wifi tethering to my phone. It is also paired to my phone via bluetooth.

I'd like to send my ETA on an SMS text to a phone contact on my connected phone, as opposed to email through the tethere internet connection.

It would be good to see integration with other messaging & social media services, i.e. Whatsapp, Google Hangouts and Facebook.Messenger, for the purposes to sending ETA, or linking a tracking beacon.
