Hi,
maybe this can help someone:
I downloaded the mapsource locked version (from the torrent) and installed successfully on win xp 32 bit; as for other past versions I used the jetmouse keygen to unlock the map for my product id; ok, mapsource sayed it was unlocked; I cut out Italy map and trasferred to my garmin nuvi 250, but when powered on it displayed:
"No Detailed Maps Found That Support Routing"
I found that this is related to unlock so I changed a couple of time the generated key, placed .unl files, but with the same result (unlocked in mapsource, but locked img on the garmin); when I tryed to transfer only a small portion of northern Italy it worked...So I'm not sure what region caused the problem.
At the end I solved my problem by unlocking the generated img file with gimg unlocker.
