Not sure if this is even really possible, but…
I have a dream of a virtual co driver option, instead of directions to a destination it would use voice to call out things like speed, heading, user defined sensors, maybe even the nature of the road ahead if that’s possible.
You can achieve some of this with triggers and using ‘Speak text’ action. You can use this action to speak values with tag:
[VALUE:#]
Where # is the value id number http://realdash.net/manuals/targetid.php
For example, to speak current vehicle speed, you can use the action to speak text:
Your current speed is [VALUE:64]
Interesting, will try it 
Got that working, it’s the degree of flexibility built into everything in RD which makes it so useful.
Probably you should be charging a bit more lol.
