wow, i thought i was just asking a dumb question. Now i see that this has been a complicated, confusing issue that has not been consistently resolved between units. Regarding speed issue, i will take the unit out on my ocean kayak where we travel at around 3mile/hours and clear line of site and of course flat terrain. Curious if my known distance and stopped time are correct.
You would think that garmin is aware of this and would have a firmware update.
thx again for your thoughtful responses!
