You will need to update the maps again.

THERE ARE A NUMBER OF SOFTWARE UPDATES IN THE LAST FEW MONTHS CAUSING PROBLEMS GO TO WWW.GARMIN.COM/SUPPORT
DOWN LOAD NEW SOFTWARE UPDATES

RESET IT OR U MAY GET THE NEW UPDATES FROM THE WEB/ GARMIN.COM

I can help you reset and fix your Garmin Nuvi 265WT.

Erratic behavior is an indication that the firmware / system software inside your GPS has been corrupted.

Satellite reception is one of the issues addressed in Garmin Nuvi 265WT firmware updates.

There are three steps to take to get your Nuvi 265WT running like new:

1. Back up your Favorites.
2. Perform a Hard Reset.
3. Download and then run Garmin 265WT WebUpdater to replace its firmware / system software.

I hope that helps.

Nuvi 265WT Manuals here.

Unless you are driving in a dangerously remote area of some desert, or a large city, GPS units rarely lose signal. Chances are you have a defective unit, I'd contact Garmin support: Here.
Hope this has been of some help.

When you change geographical locations with any GPS it will take a lot longer for the GPS to acquire the sattelites. Hold the GPS out in an unobstructed area and switch it on. Be patient it will acqurie the signals if it was working before you left home.

Look under settings>language>voice. Select American English and it will work again. The same thing happened to me this week on my new Garmin 750 and I took a couple of days to figure it out. Hope this helps.

Please read the solution that resolved this problem for someone else. Most likely, you have already tried this. However, the antenna of your Nuvi 660 is the same as the 3xx Nuvi series. I know this because I have worked on them.

If the above procedure does not work for you, the entire antenna assembly will need to be replaced.
The other option is to purchase an external antenna for your Nuvi and plug it into the external antenna port (gold connector) on the Nuvi antenna assembly.

Best wishes,

How old is the gps, if you answer is more than 2 years could mean you have a bad antenna, i would look into purchasing the extended antenna from the manufacturer if its not too expensive to test that theory.
