This is a common problem with the Nuvi series. The on/off switch is a surface mount switch that is mounted vertically off of the main PC board.

The problem is, that there is no support behind the switch, so when you press down the button, the solder leads of the switch are stressed and eventually break off the main PC board. This is a design flaw and could have been easily prevented by wedging a small piece of plastic between the rear of the switch and the SD card housing to give the switch support.

Also, the solder pads for the mechanical connections of the switch could have been made bigger, allowing for more surface area and more solder application.

I have repaired many of these before and the repairs I make prevent this from happening again.

If you would like for me to reasonably repair your GPS, please email me at KS3R at sharc dot net.

I've been using after market chargers in car and on ac. They worked fine for a long time. Now, my Garmin NUVI 660 seems to turn off (goes into "charge mode" or something) when I plug my car charger into...


Yes, many aftermarket chargers are not wired the same as a Garmin charger and will cause your Nuvi to think it's connected to a PC. What happened to the original charger that plugged into the cradle (the part your Nuvi snaps into?)

Garmin Nuvi 660 shut itself off and will not turn back on


Hi Sherry,

The unit should not get warm, unless the battery was fully discharged or maybe shorted out. Most likely a part has failed on the main board.

How do I turn off our garmin nuvi?


Hi,

Reset button behind the Antenna, press this in for a few seconds.
Use the Web-updater at Garmin, to update it too,
Jack it to a PC and run the update,
If still playing up, Use the Firmware update at Garmin for it,
(( google Garmin 660 software updates ))
Should be good then
Regards
Richard.

Charging doesn't display map when charging


I learned that with the unit off - hold the on button down - don't release it. A PRE-BOOT MODE message will appear at the bottom and may flash. Continue holding down the start button. The first time I did it a series of dots came on the screen and I was instructed to touch each one. After that it started as normal. I plugged into a wall charger and but git the pc and nuvi icons again. I repeated the process - holding the on button on and let the PRE-BOOT MODE appear and kept holding but this time a different message came on and then the PRE-BOOT MODE appeared again. I let it go and took the unit to my car and plugged it into the Garmin car charger and it worked as it used to - normal. However, when I plugged it back in the house to the wall charged I got the pc and nuvi icon again. It appears that I am using the wrong wall charger as a previous writes stated. But the nuvi still worked in the car plugged into the nuvi charger. I hope this helps.

Garmin Nuvi 660 shutting off


It sounds like your battery is defective. They can be replaced. The Motorola phone cable is not wired exactly like the Garmin, and your Nuvi thinks it's connected to a PC. Radio Shack carries a charger for the Nuvi. I have one myself.

Let me know if you need additional help with your battery problem.

Issues with new Garmin


Try pushing the reset button and charging again. If that doesn't work I think you've got a defective unit. Contact the seller and sendit back for a trade.
