"Can't Unlock Maps"

I get a "can't unlock maps" message after loading a Bluechart map onto my eTrex Legend C. The map loads fine and I can view it on my computer, just not in the Garmin unit ... any ideas?

I do have the 25 digit code.

Contact Garmin regarding the unlock code as this is specific for your unit.

Gps has lost its maps, screen says can't unlock maps


There several reasons you may receive the message Can't Unlock Maps on your nuvi or zumo device.
  • Can you press OK and get to the Where To/View map screen?
  • Did you load maps to the unit using the MapSource or MapInstall program?
  • Did you load maps to an SD data card?

If one of the points above applies to you, please follow the steps below to clear the Can't Unlock Maps message:
  1. Remove SD card from unit, if applicable.
  2. Plug the unit into your computer with a compatible USB cable.
  3. Open MyComputer/Computer icon. (Mac users skip this step.)
  4. Right-Click on the Garmin drive and select Open. (Mac users can locate the Garmin drive mounted on the Desktop.)
  5. Open the Garmin folder.1
  6. Locate a file named gmapsupp.img
  7. Right-Click and delete file named gmapsupp.img
  8. Safely disconnect your unit from your computer to see if the Can't Unlock Maps message is gone.

1. Nuvi 1100/1200/1300/1400/1600/3700 and Zumo 665 users will open the Map folder instead.

*If the gmapsupp.img file does not appear in the Garmin folder, please create an unlock file for device.

I can't put maps on my Garmin etrex legend HCx


Your MicroSD card may be full just from the basic maps. Try larger card for additional maps. The vendors supply the minimum to keep the cost low and then force the customer to upgrade the resources at their own expense.

HOW DO YOU LOAD MAPS TO THE GPS UNIT?


You will need to load the MapSource software on your PC then load the maps into MapSource. After the maps are loaded and unlocked you can plug your GPS into your PC with the USB cable and load the maps.

Hope this Helps.

No, Garmin maps will not work on a Magellan Triton.

Yes, you can install Bluechart and CityNavigator onto one SD card. Inside Mapsource, select the Bluechart maps you want, then switch to CityNavigator and select the maps you want from then, and then send all at once to the GPS unit. If you send Bluechart maps, and then CityNavigator, the CityNavigator will overwrite the Bluecharts. This is why it must be done all in one step.

Geocaching with Garmin Etrex Legend CX


The preloaded maps are VERY generic, mostly major highways. They are not useful for geocaching.

The good news is that you can download free topo maps created by a very generous Canadian soul, Dale Atkin. The maps are free but donations are accepted. He is also working on US topo maps. I've used Ibycus and Garmin topo maps and prefer the Ibycus version.
If this solves your situation, please come back and rate our answer. Thankyou.

Map down load


You can view segments of the maps at the Garmin site and it will show you how much detail there is.
Go to http://www8.garmin.com/cartography/mapSource/topous.jsp#
and on the far right side of the page, you'll see a link to Mapsource Map Viewer Topo USA 2008. Click on that and zoom in to your area.
Yes, you can download the map segments to your unit.
