Ttn application
From OpenTom
In TomTom's original images there's an application called "ttn". This is what does the real navigation stuff. It provides the UI, reads the maps and calculates the routes.
when you get yourself to a shell you can copy the ttn application (/bin/ttn) to the sdcard (/mnt/sdcard). after this, you can copy it off the sdcard with the usb interface.
if you have a serial port connected to the unit, you could use rsz to copy ttn from the unit as well.
Please be aware that ttn is copyrighted by TomTom and may not be published.
If you would like to change by your own name, you must change in the kernel code.
ttn calls /etc/rc.suspend and /etc/rc.resume scripts after displaying the splash screen and before performing respectively the suspend and resume events. These scripts can be modified to perform custom actions upon these events (e.g., in order to increase the splash time, a sleep can be added inside each script).
The file formats of the Itinerary and POI files used by TTGO can be found here: http://www.tomtom.com/support/ce/downloads/ttnavsdk3_manual.pdf
Custom TTN application
With TTGO version 5, if a file named ttn can be placed in the root directory of the SD (/mnt/sdcard/ttn); this file is executed in place of the default /bin/ttn application. It can be a shell script also. For example, a script can be developed to wrap the real /bin/ttn application. See e.g. the Event_Logger Tool.
