Probably perhaps nobody has written it. The link you gave doesn't link much 
information about the format.
Is it the vector format described at http://sourceforge.net/projects/garmin-
img/?source=typ_redirect ?
If so, a quick skimming of it would lend me thinking that read support should 
be possible, although likely not a trivial effort (41 pages for an unformal 
specification is quite significant). Write support and interoperability with 
Garmin devices would probably be harder as I can see quite a few ??? in the 
document.
