The unique capability of the Opentracker is that it can activate the
Garmin's
built-in "FMI" (Fleet Management Interface) firmware to do two-way text
messaging on the Garmin's touch screen. (It uses the same virtual
on-screen
keyboard you normally use to look up addresses for navigation). It also
will
plot incoming posits on the Garmin's map display.
Unfortunately, all this "coolness" only works with the now-discontinued
Nuvi
350. (Garmin screwed up the waypoint handling, used to plot the posits,
in
later versions of the Nuvi.)
I don't suppose Scott has made any updates after this post:Subject: Re: [aprssig] "Smart" vs. "dumb" trackers

waypoint deletion, so the T2 and GTRANS can delete old waypoints. The

at inconsistent zoom levels, with a narrow range - maybe 2 or 3 zoom
levels,it seems to be variable - and they don't show labels unless you touch them.
If Garmin gets this fixed, we'll be in good shape. FMI 2.5 added not only
deletion capability, but also categories, so everything the T2 or GTRANS

But looking around at http://www.argentdata.com I don't see where Scott
suggests further support for the newer specs yet, or if they've achieved
what he was hoping for.
