Garmin etrex legend cx (the grey one)

I recently tried to upload the Garmin City Navigator NT v7 software (most recent copy) and cannot use it. The message I get is "Can't Unlock Maps." I have the pass key and entered in correctly. Any ideas?

Call Garmin and they'll double-check the key you've entered with their system to see if it's correct. You might have just entered it wrong. The 25 digit code you enter is a combination of the software code and your unit code. If you gave the incorrect unit ID to the Garmin people, they would then have given you a key which would be incorrect.

Do you run the software with administrative rights? If you do, I have no suggestion...

Go to the website and download updated drivers/software for the unit. Make sure the drivers are for your specific unit as they are all different.

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.

Unlocking a Garmin etrex venture cx

The unit comes with a base map. You will need to purchase City Navigator software if you want more detailed maps which will show all roads. If the box contained a copy of the City Navigator and you threw away the code, you'll have to purchase another unlock code from Garmin.
