Question about Garmin Nuvi 660 GPS Receiver
Sorry for the long answer,
but the details may help someone with the other problems I ran into.
First a little background so that you can see if you have a similar experience. Skip this part if you want to try my fix for the problem. I have a Nuvi 205 and it ran out of internal memory so it could not complete map updates. I got the "No Detailed Maps Found That Support Routing" or "No Map Data Available" warning. To fix this, I downloaded and installed the MapInstall program from Garmin's website and used it to install another copy of the current map. I downloaded that copy to the computer - "installed it to the computer" in Garmin speak. Use the Garmin Express program to get the date file (Device>Advanced tab) and then installed it on the memory card I have in the Garmin unit using MapInstall.
That got the map installed on the unit and resolved the no map data warning. However, the new map did not have the local streets, speed limits, etc. I could not search for roads or POIs. I only saw highways. Spoken directions did not include exits, etc.
Next, I moved the old existing data files from the Garmin folder on the device to my computer. I'm not sure how safe this is, but I wanted Garmin Express to have some room to install the maps as it was designed to do. I figured I could put them back if everything went wrong. It booted up okay and worked as before, so I used Garmin Express to do a "normal" update. With the space available on the internal memory, the update went smoothly. Still, I had no local streets, towns, etc.
I realized the data must be there now, so I looked through the menus on the device. What I found was that the maps weren't selected. Here's where I found it on my Nuvi 205:
Menu > Tools > Settings > Map > Map Info
If the checkbox is unchecked, check it. That will tell the Garmin unit to use that map data and should restore the maps and other features for you.

It sounds like you may have just deselected the maps.
go to tools settings map then map info(bottom of the screen)
check that there is a tick next to your mapset if not just tap the name of the map and you should be sorted out.
