for my yellow eTrex, not exactly the most recent model. I can save
multiple tracks, up to 10 if I recall right, but the active trak log is
still limited to a certain number of points (~2000).  If this number is
reached, the tracklog starts overwriting the oldest points.  In other
word on a long trip you will loose the beginning of the trip.  Can be a
problem if you planed to use trackback to get back home.   As far as I
know newer units still have the same restrictions on points in the active
log, therefore the problem remains basically the same.  It's good advice
to save traks as soon as the memory indicates 95% usage.  But you'lll
need to check the display frequently to save in time.  There is not
automatic function to do that for you.  A disadvantage of saving the
active log into the memory of the unit is taht some information is lost
(time/altitude), therefore speed calculations will not work
anymore........Great if you can use a notebook or palm to do the data
capturing. Garmin seems to be #1.  Most of the software -espcl. free- or
shareware- is made for Garmin, and most of this software is for the PC.I
am using gartrip (www.gartrip.de), a shareware program and found that the
one easiest to use and to give me the functions I need now. Ulli
