i downloaded that updated 3d map file from garmin and that gave me the errors "Cannot unlock maps" that it was supposed to take care of. with the 3d file included in the OP here, i dont get that error. btw, does anyone see the 3d map listed separately in their list of maps on the nuvi unit? i thought it used to list the 3d map and the full map as separate maps with chechmark next to them. i dont see that with this latest 2011 map. is my unit even loading the 3d map?
