Thanks for that observation, AKODIAK, however i wasn't trying to offer any solution to the specific problem with recent units' map authentication and in any case your solution is regarding patching MS, BC &/or MI exe which is for something else again entirely of quite long-standing. It certainly does not overcome the recent map authentication problem in new units and is unrelated to it: [Only registered and activated users can see links. ].

Actually, all this is OT here anyway being this is an OSM map thread. To further explain my post you've quoted above, i was simply stating that OSM maps can be used as a good alternative to Garmin's NT maps in the two types of units which cannot use them i.e. the very old [non-NT] units and the very new.
