Mapsource update CD

I have just updated the mapsource to 2008. Everything downloaded successfully but my nuvi 660 now tells me it cannot unlock the maps. I entered the unlock code successfully but the unit just freezes on me.
What can I do

    Yes I have the same problem. I paid Garmin for an unlock code for City Navigator Australia 2008. The unlock code I received said the region is City Navigator Australia NT 2008 Deluxe All. Are they both the same? I unlocked City Navigator on 27 December 2007 and sent and email to Garmin that the code would not unlock the maps. I have not received a reply from Garmin. I have reinstalled the maps into Mapsouce several times but the unlock code does not work. The Nuvi 660 can not unlock maps

    I have a Garmin 660. When trying to update the Aust 2008 maps a window pops up saying. The map update on the Garmin GPS has failed. Press retry to update again. Other updates on this disc have been installed with no problems. I have two PC's one with Vista the other wth XP both givnig same displayed window. Have emailed tech support but they said setting in my PC is not set up correctly. I doubt this as two different operating systems giving the same result.

    I have a similar problem, I bought my Nuvi 660 in August 07, and was sent the update city Navigator Australia Update for 08. I have tried uploading it and the computer says its been updated, I enter my unlock code in and everything is fine until I return to the compter menu which asks you to unlock the updated maps on the GPS, then a warning comes up saying there is an error and it can't be updated, so I press 'Retry' and it does the same I havn't got anywhere. Any suggestions?

Hi check out this wed site, it will help. HT maps for the Nuvi are NOT for PC use. The map load onto the GPS as you install Mapsouce. Reinstall Mapsouce and take option 3 on the startup page of the program.

Good luck

Most likely you had the 2007 or 2008 maps. Click on the wrench icon, then the maps symbol and then the word "info" or "about" and you should see the current map revision. If you updated it recently, it should now show 2009.

I cant download mapsource to install my australian map cd

If the CD is from Garmin, it will already have Mapsource on it, and it will install when it is installing your maps onto PC. If you ever install any other maps, the CD will check to see if Mapsource is already installed and will skip this procedure.

New Maps - Can't update unit

The new maps will be unlocked to your GPS using the code Garmin supplied you.

You will have to add these maps to a second SD card if your present card is full, or else purchase a larger card. Since all the Mapsource NT 2008 Europe maps are 1,395MB in size, you'll need to purchase at least a 2GB SD card.

Nuvi 660 MapSource


You cannot replace American maps with European maps.  Garmin does this in order to protect the European retailers.  The European SD card eliminates the need to load the maps into the 660, however, if you need to use the card slot to store extra data such as MP3s then you might be better off buying the 670.
