on top of the device there is a lock slide switch, make sure its not on the lock symbol, other wise it will lock the screen touch feature.

Have you tried resetting it? My old Garmin started doing this, and resetting helped. You reset it by hold lower right corner while powering on device. Please note that all user data will be gone. This can also happen if device was on for long time and battery was drained to much

Hi, you can get the serial number by searching one of the various papers that accompanied the Garmin Nuvi when you bought it. In the box, somewhere, is a yellow sheet. If you look at the bottom of the sheet, you will find serial number as well as registration code in small black letter at the bottom of the page.
But should in case you did not get the Garmin Nuvi brand new (maybe fairly used), then you have to contact the person you got it from to get the serial number because without it you cannot complete your registration.

Here is Garmin technical support telephone number and fax

1-800-800-1020 or 913-397-8200 (Telephone number)
913-397-8282 (Fax)

Take care

This is because one or more contacts on the headphone jack have been pulled up from the printed circuit board. A detailed description can be found here:http://www.sharc.net/gps_audio_repair.htmIt can be repaired too. Don't try it yourself. Take it to someone who has done it before.- Jim

Please see this link for further information on speaker replacement. You may have a bad connection on the headphone jack as the speaker audio passes through a switch on the headphone jack. Most likely it is a blown speaker and there is a reason why these fail.The speakers used on this site are of a higher wattage rating than the factory standard.http://www.sharc.net/gps_audio_repair.htm- Jim

This is a common problem on the Nuvi 3xx and 6xx series and is caused by a failed component. Please see this link for troubleshooting information.http://www.sharc.net/gps_antenna_repair.htm- Jim

Yes, you have found the problem. The mini-USB jack is broken, preventing the battery from being charged. However, you can charge the battery by using the 660's snap in cradle and bypass the USB port. If you want the jack replaced, please see this link:http://www.sharc.net/gps_charger_repair.htmYou will want to fix the jack because you will not be able to update the firmware or map until the jack is fixed.- Jim

No. When you plug in the SD card, the Nuvi will load the map from your SD card. Once you get to the main menu, select the wrench symbol, then the map symbol and then "map info". You should see both the US and Europe map. Make sure the Europe map is checked. You can uncheck the US map. This is how you switch between maps. The reason why you have to have the extra map on the SD card is because the Nuvi can only have one map on it's internal drive, one at a time.

However, backing up your US map is a good idea.

Good luck,
