[aprssig] Newest model Garmin that works with d710?

I've got a working prototype of a protocol translator here that allows 
the D710 (and D700) to work with most of the newer nuvi and StreetPilot 
models.  Hopefully I'll have them in production by the end of the summer.

The hardest part so far has been getting the cable I need - I had to go 
to a company in Taiwan to produce a custom mold.  They're just starting 
production of the cables now.  Meanwhile, I'm working on shrinking the 
translator circuit down to a size that'll fit easily in a lump on the cable.

That'll only cover the models with the mini-B USB connector.  I'm still 
working on the 18-pin type.

There's more work to be done on the firmware still, but as it is, it 
generates GPRMC, GPGGA, and GPGLL sentences from the Garmin binary data. 
  It'll also take GPWPL or PKWDWPL waypoint strings and generate POIs 
for them, if the GPS unit supports it, which most don't at the moment.
