Hi Guino,
is it possible to implement a Cruise Control command? It would be nice to control the cruise control from the car in RR. I know we can get the reading of the speed from the gps receiver or from the gps software. It only takes 3 relay contacts to control it. Let's say you cruising 55mph and talk to NaviVoice and say "Cruise Control On" then it would send a command to the relay board which turns on the cruise control in the car and sets the speed to 55mph. Now if you want to go faster you would say "Speed Up" and a relay contact would close and speed up the car, same thing if you would like to go slower then we could have an indicator on the screen for Cruise on or off and the set speed.
Something like this:
