Well, i suppose you've worked it out already that these things are not like a nuvi with a visible file system. You can't hook up in MSM and look at files and folders, everything is flashed to regions. Even maps, basemap in 3, detail map in 10 but that's the CF card Garmin folder\gmapsupp.img anyway in 26xx/GW. Cardless units have rgn10 onboard and also have gmapprom.img and some have gmapoem.img in special regions too. Voices are always in rgn17 [hex 11] in this type of unit, and you're right that they're non-TTS.

I think all fw has ref's to AUDPKG (& AUDIMG too) from early 'region-only' units right thru to the most recent nuvi-type devices. Just don't ask me how it all works, ok. Here's a nice pretty unicorn for you to play with instead:
