Garmin maps

 

Hi I’ve recently purchased a Garmin Nuvi 56lm. Before this I had a Garmin 52 lm. I purchased a micro sim with USA maps on which worked great in 52 on yet when I try to put into 56lm it can’t unlock maps any ideas guys cheers

Call Garmin

I think the best approach would be to call Garmin customer support. I'm guessing here but It is possible there is something in the license agreement for the micro SD card that makes it usable in only one GPS. The lifetime map download feature on your Nuvi's may not apply to maps purchased on fixed media.

Map transfers

Jimbob, assuming the map on your SD card in the 52LM was a genuine Garmin City Navigator map from a map update performed online, even though it's on a SD card, the map files are locked to the 52LM. Transferring the SD card to any other Garmin device will result in a locked message as you've found. If this is the issue, use your 56LM connected to the internet and obtain a map update for it onto a different SD card.

On the other hand, if the SD card was purchased from Garmin with a Garmin map (like if your device came with a European map and you wanted to obtain a map of North America on a SD card straight from Garmin), then the map should work in any Garmin unit capable of using that map and this seems to be the issue you're having. Certainly, a genuine Garmin-made standalone map on SD card that works in the 52LM should work in the 56LM, even if purchased used from eBay or elsewhere. If this is the problem, maybe the 56LM's SD contacts need cleaning. Note though, that these maps are locked to the original Garmin-provided SD card. You can not make a copy that will work for you of the SD card onto another SD card.

If you're using a map on the SD card that isn't a genuine Garmin-made map, please let us know now (like an OSM map). Also, if you're asking about a genuine Garmin map that you've obtained from a questionable source, this site will not offer help.
