    I would not attempt this repair yourself unless you have soldering skills and experience with surface mount technology and the proper equipment to unsolder & solder surface mount parts.

    You take the risk of further damaging your Nuvi.

    Contact me directly at ks3r at sharc dot net if you are interested in having me repair your unit for you for a reasonable price.

SOURCE: nuvi 350 on off problems

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 I'll be posting a step-by-step procedure on how to fix this and prevent it from happening again.

I must point out however, that in order to make this repair, you will need to have skills in dissassembly and soldering.

Also, please only attempt this procedure if your unit is out of warranty.

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

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?

not sure if you are keeping the tab open but...the reason is because the tab at the top of the GPS is the antannae. You have to open it or it won't work. when you press the reset button, you are opening the antannae first which then acquires the satellites. Keep the top tab open.

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.
