Enables WIFI hotspot Tethering on phone so Android car stereo can auto connect and have internet when it detects the hotspot.
My phone first connects automatically via Bluetooth (as I always leave blutooth on), this detects the blutooth connection and then enables tethering.
You will need to edit the Bluetooth sections to set your device it connects to. I also normally have the volume set to zero on my phone, this changes it to 100% when in the car (so it can tell me when it's connected) and sets back to zero when it disconnects; modify to your preferred normal volume. It will also re- enabling normal wireless on my phone when Blutooth disconnects.
