All TomTom's I've seen start in USB-storage mode without help from ttsystem or any other software on the flash/harddisk. > Other questions : > > - other Tomtom models appear to have some kind of special connector > through which the serial console can be grabbed.

Not a real serial console, that would be very hard to do in would involve quite a bit of soldering. You can however get a console over bluetooth, search for btconsole. > > - the device has a «reset» button, but its behaviour is unclear. Does > it simply do an hard reboot, or does it restore something special ? Well, my guess is that that would do an actual reset as opposed to switching between sleep modes that the power button does. So this reset button would clear the contents of the ram, while the powerbutton doesn't. Regards, Wander.
