Can't Unlock Maps

Just was given a Nuvi 200 as a gift. Downloaded latest firmware and map updates.
When I turn the unit on, it initializes, loads maps, gives the Warning screen, and then gives a screen "Can't Unlock Maps". I click Ok and it goes to the "Where to/View Map screen. If I go into the maps, it appears I'm viewing them OK - but I don't know if they should be any different than they are as I've never seen another unit in operation. Why am I getting the "Can't Unlock Maps" screen??

I also have MapSource (have an Etrex Legend) but don't think I tried to install maps from that - but might have. How would I know?

Nuvi 200 Settings/Map/Map Info says "City navigator North America NT 2009"
then under that:
"[1] ALBERTA, SASKATCHEWAN, MANITOBA, BRITI" (rest off the screen)
"[2] ONTARIO, NEW BRUNSWICK - P.E.I. - NOVA SC" (rest off screen)
Thanks for your replies

1. The GPS unit is missing the unlock code;
2. Locked supplemental maps have been downloaded to the GPS; or;
3. Locked supplemental maps have been downloaded onto the SD card.
Go to "www.My Garmin.com" and under "FAQs" do a search for "Can't Unlock Maps". There is a complete how-to to get rid of the message.
I found the link. Almost worked! I noted that the GMAPPROM.UNL file had my Product Code in it rather than my Unlock Code. Put the right code in however still get the Can't Unlock maps error. Removed SD card and error still there - so problem is with the unit;not the card. Removed the supplemental maps image and got an error saying there were no maps. Reinstalled the CDN maps with Mapinstall. Still getting the error. Frustrating. Will try Garmin support later today.

My problem was that apparently the unit originally came with 2008 maps. Somehow during the auto-upgrade it appears the transfer may have been interrupted and restarted or something (supposition only). Anyway, the 2009 maps were installed as supplemental ones with the 2008s staying as the main ones. Unlock code was fine for the 2009s but was overwritten for the 2008s. The original maps were what was giving the error and I could still use the maps because the 2009s were unlocked.
As per direction of "James" at Garmin, I deleted both the gmapprom.img and gmapsupp.img files from the unit. Reinstalled all maps with Mapinstall (these were named as gmapsupp.img); renamed the gmapsupp file to gmapprom and voila! No errors and I have more space free on the unit!
Thought I should post the fix in the event someone else experiences the same problem. Thanks again for all your help.

Thanks !
Here is how I did it.
1.Uninstall ALL Garmin programs from PC
2.Delete all files in "MAP" folder on GPS Unit then unplug unit from PC
3.Run regedit on PC and remove all references to "Garmin or Mapsource" - Make backup of registry first. MAKE SURE TO DELETE CONTAINING FOLDER AS WELL IN REGISTRY IF IT ONLY RELATES TO GARMIN.
4.Restart PC
5.Plug GPS Unit in and it should show as new hardware.
6.Re-install Maps
and VOILA all should be well.
WARNING - BE CAREFUL IF YOU ARE NOT USED TO USING REGEDIT
