    We live in Pennsylvania and we took our Garmin Nuvi 660 to California. It worked there for a while . Then it lost satellite connections. From then on up until today (that's over a month now) it still can get any satellite feed/connection & we're back in PA already. How do we acquire back that satellite connection?

    I have purchased my GPS in Dec.2006 and it will not aquire sattelites.I paid $1024.00 incl. taxes for it at that time and am quite dissapointed in the short performance of it.I realize they have dropped significantly in price and I can get a recond. one for $327.00 incl. taxes. Should I abandon this product and get another one? P. Schlecht

    I had the same problem with my Nuvi 660 where it wouldn't see any satellites. I connected an external antenna and it started to work again.

    Trying to contact Garmin to see if there is a recall on this since so many people are having problems with it.

I've tried master resets and it does not fix the problem. Only fix is to buy a $30 garmin reciever extension and attach it to the side of your flip up receiver. This is the only fix.

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 problem.

Make sure you have a clear, wide view of the sky - the GPS needs to have a direct view of at least 3-4 satellites to triangulate your location. If there are tall trees or buildings around it won't be able to.

No unlock code for Garmin Nuvi 660

Sorry but that is a security feature. There is a chance you've purchased a stolen unit from ebay. Unfortunately, only Garmin can unlock it and they will require a receipt from a Garmin dealer.
