Garmin nuvi 660 suddenly stops working in route to destination
I was on a trip to Mississippi--Garmin got me there fine. On my way home, I was on a major highway and it just suddenly told me to turn on a street that was not there...Then on the Garmin device, the car left the road and was off in the 'black area'....The Garmin continued to tell me to make turns that were not available. I finally cut if off and relied on my memory to get me home. I turned the Garmin on again when I was closer to my destination and it was fine. Any suggestions?

There should be a built in trip planner app to set up your trip. If it is a long trip and you don't like the route just add a stop for gas or food along the route you want to take. If it is a short trip then get over the fact it is recommending something different, mute, it and drive how you want to go. It is a computer and does not know what you may know. As an alternative, add a via point by telling it a new destination while it already has one. For via points remember to work backwards. Final destination, then next to last and so on.
The Nuvi you have does not support multiple destinations in a route. you can have 1 destination and 1 via point. So if you are going to a destination and you need to add a stop in the route, you can add the 2nd point to go to and then continue to the original destination.
Have you loaded a lot of JPGs or MP3s on the internal memory? If so, you have reduced the amount of memory available to the 660's OS. Not sure if the 660 stores calculated routes directly to the internal flash memory, but it is very likely, since it keeps your route when you power it down.
To unload the internal memory, consider buying an SD card - they are cheap right now. As a matter of fact, I just ordered an 8GB SD card for my 660 from Amazon for $13. The 4GB and 2GB cards are available for about $7 and $3 respectively. Drrrrrt cheap!
You can access the internal memory of the 660 on your computer with the USB cable you got with the 660. The two folders to focus on are the JPEG and MP3 folders. Simply copy these folders' contents to the root directory of the SD card, and then go into each folder in the GPS memory and delete the MP3s and JPEGs you added - should work better. The 660 will recognize the files on the card if left in folders named identically to the folders in the internal memory.
If you didn't add any content to the internal memory, that is a different issue altogether, probably something to discuss with Garmin. Could be as simple as upgrading the firmware. Make sure you select the correct version though, or it could be a fancy brick! Go here for the nuvi 660:
Have you selected how you want to get there, shortest distance, or fastest trip. You can set these under the wrench menu, If you aim for fastest, usually it will select all highway, if you select shortest distance it will calculate a trip that will drag you through every nook and cranny, usually quite entertaing (sightseeing)

memory full was being displayed on screen whilst on destination ,sometimes followed by route waypoint memory full .
I found by turning unit off , then holding finger on top left of screen ,and at the same time turning back on again the unit would go into maintenance mode.
Follow prompts on screen to reset waypoint memory.
Mine works as good as gold now,hope this helps!
