No, sorry it can't dump. That was just a brain-fart on my part. Because I posted in a hurry i'd unwittingly written G7ToWin when i meant GPSDaemon. Some Garmin older devices also have shown to be stubborn when trying to dump regions with GPSDaemon. For example StreetPilot c3x0 series doesn't yield any results in my experience using the methods described in posts 33-35, as confirmed in P#36. I guess you tried all the listed methods for the astro.

Did you try flashing PouchX's modified fw in it's original form (FR not EN)? If that works properly then it might be that the EN blocks are larger than the FR blocks you replaced. The same or less size for the language blocks is acceptable but an increase isn't.

Would you kindly post a link to PouchX's V3.52 please, I had it on an old drive somewhere but can't find it now.
