Re: [gpsstash] Emap temperature readings


Yes, there actually is a thermometer inside Garmin GPS's - it's used to help
compenstate the internal clock for the thermal changes in the frequency of
the crystal. However, it's not exactly reliable, since the electronics
themselves (and your hand, etc) generate heat as well. See

for more details on how to get to it-
