Whats the plan

Many thriftstores have huge piles of these little linux devices with bad batteries and ancient maps.

Seeing that most of this stuff is actually open and usuable, refurbish them somewhat?

Useful stuff to know

• The USB port for charging is also a OTG port (at least on OneXL)
• If you have USB connected on powerup to a PC , the bootloader gives you full access to the internal flash (on models that have that)
• Week rollover is a thing that might prevent GPS link? https://wiki.navit-project.org/index.php/TomTom#GPS_and_GPS_week_rollover
• 'ttsystem' file on disk is kernel + initrd , opentom comes with a 'ttimgextract' tool , check opentom's README.md

Works?

David built some images and sent them by PM , these already gave me something working on the OneXL.
