Hi Boyd,
Yes it’s a hassle. IIRC, there was an unlocker, and I’m sure I’d have had the forethought to do that for the compiled gmapsupp.img files that I backed up.
I’ve found the MetroGuide CD but that doesn’t autoroute, and I’ve found the City Navigator case without the CD itself lol.
I had a fiddle last night with an img file splitter, and another tool to install that to MapSource,
which is how I got this topographic on the device that I made myself.
For the City Navigator maps though, everything appears to work until I select that map set in MapSource, and it tells me something is wrong with the map.
Maybe these tools had issues with auto routing map sets?
Funny now that even if I wanted to install MetroGuide from my CD (which I don’t),
that would probably not work now as you said, and I’d need hack tools to do it.
As a last resort I might buy this Garmin Data Card USB reader and hope that the file on it
is the same old gmapsupp.img file that can simply be written from the file I have.
If not, I guess I’m boned.
