My garmin Nuvi 660 lost its satellite connection on the middle of a trip yesterday and couldn't locate the satellite afterwords. It freezes up at the aquiring satellite mode for ever. I updated all the firmwares using the Garmin webupdater today. Now it sits at the locating satellite screen and doesn't lock to any satellite at all. I cannot register with Garmin as I don't have the yellow paper with the Garmin registration code as it was an openbox customer return item. Could anyone please help me to fix this problem. I am having the same problem as everyone else and Garmin has given me the same runaround. The problem with the losing of the satelittes started right after I used Webupdater and downloaded their last update. Garmin gave me a website that some guy has saved all the old Garmin software ( I guess he knew their may be a future problem with Garmin) it is www.gpsinformation.org/perry/ I returned my GPS software back to ver.2.70 for my Quest 2 and the problem with the satellite dropouts are a little less frequent. Garmin said that they do not endorse this website and to use at my own risk. I will stuggle along with this until I can afford a Maggellin GPS
My Nuvi 660 lost its satellite connection while ago and did all update and it didn't help until I bought GA 25MCX Low Profile Antenna off ebay and guess what? now I get full signal and I don't mind having another cable attached to my Garmin.
Please read this solution, which might help you. On the 660, you press and hold the upper-left hand corner of the screen while turning on.

Try this and see if it fixes your problem....first disable bluetooth then follow these steps.
1. Power off the unit.
2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least).
3. Once the pre boot mode message disappears release the power button and your device will perform some activites to recover from the above problem.
