No maps - Garmin Nuvi 660 GPS Receiver

Check the map menu to see if the new map is on the unit. At the main menu, press the tools button then the map icon. Then press the "map info" button. Look to see if the listing shows the new map that you just downloaded or if the original older map is still there. Make sure that the map is enabled by a check mark next to the map listing.

There are 2 possible reasons for it to say there are no detailed map available. The most likely reason is that no map is selected. Press Tools, then Press Settings, then press Map and then Map Info. There should be a tick beside the name of the map installed on the satnav. If not press the map name to select it. A tick will appear at the side of the map.

The other reason is that the map may be locked. You'll need to go to My Garmin, and then Maps to get the unlock code.

If you already have a map on your unit, you will have both maps. You may have to enable the map on the SD card. At the main menu, press the wrench symbol, then the map icon and then "map info". You should see all of your maps that are available to your unit. Make sure that the square boxes next to each map are checked. Thats how you turn on/off (selct) each map. If the SD card map isn't working, make sure it has a unlock code assigned to the map or it won't work on your unit. Also, the map file name on an SD card is different than the name on your unit. - Jim

Hi, Answers to your 2 questions 1 and 2 . ...... 1/ go into PREFERENCES , hit right arow key till you see MANAGE MAPS , Tap that MAP icon and in there will be all the maps you have on the SD card. Select the map you require by tapping the screen. ............................................. 2/ YES , backup the SD card to your PC first. ( you should save everything on the card as it is ) Then delete the Europe map off the SD card and replace it with the USA map . You will need the authorisation code for the USA map in order to activate it. When you return you can swap the maps back again.
