If they don't give you a new one under warranty because of the broken powerbutton,there are third party Garmin repair services that will fix it for cheap. Also, I found an DYI GPS repair guide,so you can do it yourself too, not that difficult. The part is on Ebay.

This is a common problem with the Nuvi series. It's a design flaw. 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.

If you would like for me to repair your GPS for a very reasonable price, please email me at KS3R at sharc dot net. I repair the unit and reinforce the switch so it won't happen again.

    Note to all Garmin Nuvi 350 Users with a Defective On/Off Switch:

    1. In order to repair this problem, you need to have surface mount desoldering/soldering skills as well as the appropriate soldering tools and case dissassembly tools. Without these things, you take the risk of further damaging your Nuvi, possibly making it impossible to repair.

    2. Resoldering the switch is not going to resolve the issue long-term. In some cases, the switch can not be resoldered and additional rework must be performed.

    3. In order to fix this problem once and for all, the switch needs to be mechanically secured better to the main PCB using pre-tinned buswire. In addition, a custom-fit piece of plastic needs to be glued behind the switch to give it additional support.

    FAILURE TO DO THE ABOVE WILL RESULT IN THE ON/OFF SWITCH BREAKING AGAIN.... GUARANTEED!

    For a reasonable price, I will repair youf Nuvi on/off switch and put in the modications so it doesn't happen again. Repair takes 1 day, units are sent back the next day. Please contact me at KS3R at sharc dot net if interested. I have references.

I have a garmin nuvi 350. It suddenly quit. It would not power up. I bought new car charger and wall charger specifically for nuvi 350. Both charger would not power up the gps at all. Is my battery dead or...


I would say this is not a battery problem. A Nuvi will power up even with the internal battery disconnect (done it many times myself ) when connected to an external power source. Please see this link about Dead Nuvi's. Have you tried pressing the reset button behind the antenna?

I bought a garmin nuvi 350 at a flea


Take it back and get your money back, as it is probably stolen. The PIN cannot be broken as it is set by the original user and cannot be reset by a third party. Even Garmin will not reset it without the original receipt from a Garmin dealer.

Gqrmin 350 GPS Receiver wont turn on


Dead Battery? That makes no sense at all. He mentioned he was running it off the battery - " I was able to plug it in to a computer1.gif and unplug and was able to use it on the battery. Once I unplug and use it on battery, the only way I can power it off is by pressing the Reset button on the back."

The fact of the matter is that there is a well known issue with Nuvi 350 Power switch. I haven't taken mine apart yet (also bad power switch), but most likely the switch is defective or the solder joints are broken.
