This is for anyone on a TW rom that does not have "Car Mode" included in the rom
Fully tested and working on KK 4.4.2
Car Mode is a fully voice controlled BT hands free service
all actions are activated by the command "Hi Galaxy"
The required files are listed below and the link is to a zip with all required files and instructions
Push the apps to system priv app and the libs to system lib
all permisssions must be rw-r-r as always
Then install the app "more shortcuts" from the play store
choose an "activities" shortcut and select "Car Mode disclaimer" from the list
a new android shortcut will now show on one of your screens
just tap this to start up "Car Mode"
S Voice must be installed and working for car mode to work
now enjoy a fully working BT Car Mode system - fully hands free and voice controlled
credit goes to @Arsaw without his advice this was not possible
