The base system is linux based (i know, i wrote some of their device
drivers). Anyway, as long as you don't zap the bootloader and make a
backup of your tomtom, you shouldn't have anything to worry about.

The opentom stuff is pretty old btw, going way back to the first models
of the tomtom. I don't know if they ever did anything with tomtom home,
which basically has nothing to do with the linux kernel iirc (it has
been a while since i worked for them).
