im having a similar issue but im using ICS. when my phone restarts it always comes up in car mode.... i hve no idea wht car mode is on ICS as it doesnt do anything but put an icon in the top of the status bar. its annoying as hell considering there are no settings, no program to turn it on or off, it cant be activated manually and there are no settings. i was told it was "dirt or dust" in one of the ports on the bottom of my phone in a different forum, that is not the case at all with this phone. anyone have any ideas how to kill this damn thing? none of the apps can recognize this app opening i guess as none of them kill it or replace it.
