2009 Navigator NT disables garmin lock???


I read that if you apply the Navigator 2009 maps, your Garmin lock feature will not work anymore.

Can someone confirm or tell us this is not true?


Not for me

The update only updates the maps. It does not mess with the firmware or software that's different from the mapset. All the settings remain the same. Only difference there is that the Map Info will disply it has 2009 maps and below it lists every state in the US or Canada if you selected them.

I've got a nuvi 650 and downloaded NA 2009 maps a few days ago and my lock works fine. Got a firmware update as well and no problems there. Took about 1/2 hour to update the maps.

Hope that helps,

See this topic for an in-depth discussion of the Garmin Lock - to use or not to use, that is the question! confused

No problem

I updated my Nuvi 350 with CN NT 2009 and the Garmin lock code stills works as it always did.

CN NT 2009 update...Nuvi 250w, Mapsource 6.13.7

All went smooth for me too, firmware and the mapping. It even kept my favorites, POI files, and Topo maps that were previously uploaded all intact. The Garmin Lock doesnt seem broken to me either.
