Question about GPS Devices
It took about 45minutes of holding on Garmin's tech support line but when I finally got through here's what they'll ask you.
1) Have you tried a hard reset?
-Just push the reset button on the back below the GPS antena
2) Have you updated the software to the most current version?
-Run the Garmin web update utility after you've connected your GPS receiver to your PC via USB. Update the software (current version 5.6) and the GPS Chipset Software (current version 3.0)
3) Have you tried a master reset?
-WARNING THIS COULD ERASE YOUR ENTIRE FAVORITES SECTION. But you turn off the GPS push on the top right hand corner of the screen while you power up the unit and it will ask you if you want to perform a master reset.
After you've done all this (and you can save yourself some time by just doing it before you call) they'll tell you its probabbly a diode in the unit that controls the antena. See that little gold looking hole in the GPS antena? That's where you can connect the external antena the diode the controls where the unit gets its satellite signals from (IE from internal or external antena) is known to mess up if the unit is left in extreme heat (a hot car would do it) however aparently since this is such a common problem Garmin is accepting RMA's for the units even if their several weeks out of warentee (mine was and i just sent it off for this very same reason). More often than not they'll simply replace the unit with a refab and you'll be back in bussiness in no time. Hope this helps!

No. 98% of the time it took 45-56 seonds for your NUVI 660. Thats the compagny set up time acquisition and it did very well.
Be sur you had your flip antenna parallel to earth surface.
660 has THE BEST SIRF Chipset for acquiring satellite.
I had 2 NUVI 660 since 2 years. It work much better than those new 7xx series who it really took 2-3 minutes to acquire satellite.
Be sure you update your version to the last one.

Here's the solution I received from Garmin:
Thank you for contacting Garmin International.
I apologize for the inconvenience with your unit not acquiring satellites. It will need to come into us. I have set up a RMA for you to send the unit in. I just need for you to put the following information on the shipping label please.
RMA ZW 0000000
Dock Door #20
1200 E 151st St
Olathe, KS 66062
Please send the unit in by itself. Once we receive the device from you, it normally takes 7-10 days to get it back to you. If you have any other questions, please let me know.

I am having the same problem with my nuvi 350 and its about the same age. I read on another post it may need a new battery but you need to send it to garmin. I am going to contact garmin directly.

I had this problem once. I used a tiny screwdriver to reset the Nuvi through the reset button at the bottom. Make sure the antenna is down when you restart. Once you get to the main screen open the antenna only half way - like 45 degrees from the main unit. It may take a few minutes to locate the satellites.
