Power button don't work

I just bought a Garmin nuvi 350 after using it I was unable to turn it off. I had to use the reset button. To turn it on I use my usb. I need to open my GPS to fix the power switch in side. So I need to know how to get a part. Could someone help me. Is the face plate clip on. I don't see any screws. Thank's Chris

    Yea I have the same thing, Im contacting customer support to see if I can get it fixed. I think its just a bad connection.

    Same problem with a 360. Power button appears to be inoperative. Unit works, charges and turns on when attched to car. Work around is to use car to turn on unit then remove from car mount while on. Answer "no" when asked for shutdown.

    Only way to turn on is to use the car charger. Have contacted Garmen but no reply yet.

    Had the same problem on vacation. All of a sudden, the power button stopped working, and I had to resort to the reset button. Am looking for solutions too!

    I have been having the same problem for about 1 year with my Nuvi 350 - VERY ANNOYING!



    Otherwise, I was very happy with this unit; I use it in the US all the time and have twice taken it to Europe. This was an expensive piece of equipment to break in such a fundamental way.



    Until today, I was able to power on/off by plugging in the auto power cord or the computer USB connector, but I just downloaded a GPS update and that no longer seems to work.

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.

    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 think this must be a common problem. I had a Nuvi 350 replaced after RMA number for btained rom Garmin. It was still under warranty. They were very good with replacing the unit.

You need to hold the on/off button a couple of seconds before the unit will turn on. This is not an instant on/off button.

In order to take the unit apart you need to first remove the antenna. There are two torx 5 screws underneath the antenna holding the unit together.

If the unit is under warranty or if the unit is only a few days old send it to Garmin or bring it back to the store for an exchange.

Likely a mechanical failure of the power switch. I called Garmin, described the problem, got an RMA number, mailed in my 350, and received a refurbished unit in less than 1 week.

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.

I had this same problem.  Just lift up the antenna on the back, hold the reset button for 3 seconds, and then plug it in to an external power source.  Mine started right back up after just going black one day while driving and not turning back on until i did this.

Garmin Nuvi stopped working and won't restart


Got a Garmin Nuvi 260. Same problem. I read the booklet. There's a reset button on the bottom. Disconnect from power. Push the reset button. Connect back to power. Now it works. The reset button is tiny and looks more like just text on the bottom sticker than it does a button. But push it anyway.

Nuvi 350 System Software Missing


Try this: Hold the power buuton down, you will see on the lower screen the word "Pre Booting - ". Keep holding the power button for about 60 second, then you will see on the lower screen "Booting".
This time, release power button; system will reboot and loading map... again.
I got the same problem, after research on the web. Nick 99990_0 had post this solution on (his Nuvi 660) but it work for my Nuvi 350 too. Good luck.
