can you post gmaptool listings from both img, then maybe we will find the differences?

may I have more details about this issue?


edit : map unlocked with Fast IMG Unlocker is working fine in nuvi

Initially, once I have unlocked the 229 mb one with fast IMG Unlocker, I have put that on SD card (just that one and nothing else), first as gmapprom.img and then as gmapsupp.img. Both did not work. Then, I used GmapTool to split the unlocked gmapsupp.img and then just "Join"ed back the just the .IMG files using GmapTool, which created the 170 mb img file, which I then put on the SD card as gmapsupp.img (again just that one file on sd card) and it works just fine.

That was couple of hours ago....now I have tried something else, based on what I read in a prior post, about an issue with map ID > 2200....

I took the unlocked 229 mb gmapsupp.img, opened it in GmapTool, and in the "Join" option, I used, "Set mapset FID " and entered 281 (as in for the prior version of garmin nt india map) for FID and did "join all"...thats it..the 229 mb one works in my C330 now...
Not sure, if C330 being an old garmin unit, has any limitations !!
how and what are still a mystery for me..but this trail and error worked
