Driver jailbreaks car navigation to change clock
The gist
An owner of a 2014 Renault Latitude rooted its TomTom navigation unit to change the clock.
The unit only accepted clock settings with a navigation SD card inserted.
How it unfolded
- recentlyThe owner found the clock could only be set with a navigation SD card inserted, and set out to root the unit.
- recentlyAfter reverse engineering, the author concluded there was no way to reach the correct settings menu without an SD card, since the menu definition pointing to the Settings applet was read from the card itself.
