Try doing this:

1. Use Mapsource to find the unlock code for NT v8 (from Utilities->Unlock Maps...).
2. Using Notepad, edit gmapprom.unl file on the unit (under Garmin folder) to replace invalid code with the correct 25 character unlock code (no spaces or dashes) and hit Enter key and save.
3. Reboot.


Hope that helps........

The following is a solution to the “Can’t Unlock Maps” problem that a few Garmin nuvi 770 owners out there are experiencing.

  • Go to the Garmin website and register you nuvi 770
  • In your MyGarmin account, you will be able to obtain unlock codes for you GPS system. Please note that there will be two unlock codes for the nuvi 770, one for Europe and one for North America
  • Copy your unlock codes, one at a time in lowercase with no spaces or characters and save them into two separate notepad files. (For all those non-techie folk out there, you will find your Notepad on your PC in Start, Programs, Accessories, Notepad.)
  • Save the Europe unlock code as gmapprom.unl and the North America unlock code as gmapprom1.unl. If you are asked would you like to replace existing files, click yes.
  • Connect your nuvi to the PC and open it up on My Computer.
  • In the Garmin folder, paste these two new files.
  • Disconnect you nuvi and then switch it on. Your maps should now be restored.
Thanks.

Only shows us routes not canada


I fell foul of that the other way. I have Canada maps and lent it to a friend who was going to California.

You need a map that covers Canada and it is an extra cost. The USA is in two zones, or one map does both zones.

You need to buy the Canada maps and then put it on an SD card. The map costs $84

From the Garmin web site:
Question: What should I do if my Garmin nuvi / zumo displays the message "No Detailed Maps That Support Autorouting."?
Answer: Please follow these steps to troubleshoot the error message:
Checking the unit:
  1. Hold your finger down on the screen until the message "No Detailed Maps That Support Autorouting" disappears.
  2. If you get a locked maps message following this error please remove any SD cards in the device and skip down to the instructions for "Getting your unlock codes".If you did not get a locked maps message then please select tools>settings>map>mapinfo button.
  3. Check the box next to the mapping product City Navigator and you should no longer get the "No Detailed Maps That Support Autorouting" message.

She can purchase the City Navigator Australia DVD and load the Australian maps onto an SD card. Insert this into the unit and she'll then have both S Africa and Australia maps.

I am updating my nuvi 200 with map update 2009 of city navigator north america nt. Canada is not loading to my gps through my computer. Looking for a solution.


when updating from the city nav update disc, it will only update the maps currently on the unit. Since Canada isnt included, it will not add it on. What you need is the Pre-programed City navigator chip for Canada. Normally retails around $59.99

I keep getting memory full message and route waypoints full on nuvi 610/660


The Navigator memory card will come with the a countrie's maps. Maybe you need to take the memory card into the computer and download more maps. Also try to erase the nt middle east location and start over.

City Navigator Lower 48 States NT 2009


Hello parteeboy24,

The on board memory in your Nuvi 200 may not have enough free space to hold the map. You may be able to free up some space by deleting maps or language packs that you don't use. (Be careful to back up any files you are going to delete.) Or you can add an optional SD memory card to the unit to increase the storage capacity on the GPS.

Best Regards,
Ken
