"gro" files are part of one brief experiment by the NNG. They tried to create a very simple version of the WinCE software which they then called "Amigo". Of course, they also created a version for Android.
gro is "translated" into a zip file (and vice versa) by a simple algorithm (data, branding, lang/voice), therefore the supplied converter is used.

iGO 8 will not work on newer devices simply because there are no high and non-standard resolution files (data.zip)
