[aprssig] Garmin NUVI & messaging?

Bottom line as I see it: Only the Nuvi 350 does everything the way you 
would expect it to work in any of the currently available Garmin FMI 
line.  And the 350 is discontinued and only available as closeouts 

I'm still not parting with either one of mine!  The T2-135/OT2m and the 
Nuvi 350 just play too well together!
