[aprssig] Garmin nuvi 350

[Scott Miller]

It doesn't seem to be compressed.  At least, there's a lot of readable 
stuff in the ~9 MB binary file that it uploads.  In any case, it's very 
doubtful that a single file could be replaced to change it.  It's going 
to be some little piece of code buried in there somewhere, very hard to 
find without a debugger to watch it executing.

If it was running on a PC, I'd at least have a chance of tracing the 
execution and finding it, though it might still be hard to patch.

With access to the source code, I doubt it'd take more than 30 minutes 
of work.  That's the frustrating part... Garmin can do it, they just 
don't see the need.
