Can you please explain how that link is relevant to the Garmin SDK?  It is
a proprietary set of maps in Garmin format, right?  (Do you happen to know
which tools they are using in the map compilation?)

Please correct and enlighten me if I am wrong, but I think that the only
SDK that Garmin is distributing has something to do with a binary library
for Microsoft Windows and Apple Mac OS X that speaks the proprietary Garmin
protocols over USB or RS-232.  Again, as far as I know, some recent models
(Edge 605/705 at least) do not speak that protocol.  Instead, they only
implement the usb-storage driver, making the internal flash and the SD card
accessible as block devices (drive letters in Windows parlance).

I would love to hack the Garmin Edge 705 firmware to fix some annoyances,
but I haven't been able to find anything about existing efforts.  There is
a firmware hacking scene for Canon digital cameras, for instance.
