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 its under warranty, call Garmin and send it back. No need to worry about this if its under warranty.

If not, and 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.

Why do you say failed, is it wobbly, or do you mean it doesn't switch on if you tap it?
Usually you have to press it and hold it for a couple of seconds before the device spring to life.
Doesn't it switch on at all? Is the battery fully charged?

Look near the SN # and press the reset button.

with the garmin off, hold down the right bottom of the screen and turn the garmin on, it will then ask you if you want to perform a hard reset. Choose yes and that should fix your problem.

No satellite reception on garmin nuvi 350, garmin offer to repair i believe it may be the antenna as i did all the reboots do think if repaired the problem will persist


There is a possiblility that the antenna is defective. Sometimes a factory reboot helps or re-burn of the firmware. One way to confirm an antenna problem is to go into the tools menu and select "about". If the screen says "GPS S/W = 0.0 (should be a real number like 2.9 or 3.0) then this indicates that your antenna is not communicating with the main board.

Sorry to say the LCD display is cracked. You can find a replacement LCD display with tools on eBay but they are kind of pricey.

You might try finding one for sale that has an antenna problem or is completely that had a known working display at the time it died.

If you send it back to Garmin, it will cost you almost the same as a new one if your unit is out of warranty.

Good luck!

Audio problems


Steps:

1. Make sure battery is charged. Go to Step #2.
2. Press reset button and try it again. If still bad, go to step #3.
3. Try using headphones.

By using the headphones, you are bypassing the internal speakers, which might have failed. If the sound is still missing, the mostly like problem is a defective audio output stage on the motherboard.

Since this unit uses surface mount technology it will have to be sent back to the manufacturer for repair.

If the sound works with the headphones, the speakers have failed. I have seen several postings of speakers failing in the Nuvi 350.
In either case, you will need to send the unit back for repair. Be sure to have your serial number handy. Register it online https://my.garmin.com/mygarmin/marketing/register.htm

Won't acquire satellite


There is currently an Update (Vers 5.10) available at Garmin.com Check only the Nuvi 350 click on it and the Nuvi 350 will appear. In the Upper Right Corner you will see a Category of Updates. Click on it and you will be advised that you need to Download UpDater. Do so, uncompress it, then attach your Nuvi to your computer and run Update. It's simple, just follow the instructions on the screen. However, it sometimes take a couple of tries before the Nuvi actually accepts and shows that it has been updated to Vers 5.10 I guess I was lucky. Mine accepted the new update with the 2nd install but it sometimes takes 4 or more. If you are uncomfortable with the foregoing or it doesn't work for you contact Technical support at Garmin. They are really helpful and you can e-mail them at techsupp@garmin.com

Power button don't work


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.
