Re: power button failure

There is a well known issue with power switch failures on this unit. It happened to me as well. I have heard that you can power the unit on with the car charger or if you plug it into the PC using the USB interface. I will try this tonight and report back my finding. I will be taking mine apart because of my bad experience using Garmin's technical support line. Most likely the problem is a defective switch or broken solder joint where the switch connects to the motherboard. Remember also, you have to hold the switch down for a couple seconds for the unit to power up.

Re: power button failure

The switch assembly has rotated away from the circuit board losing the tongue and groove contact with the plastic slider. This may have been caused by the unit exposed to impact. It is not recommended that you open the case due to the fact you may rip the wiring harness which connects the LCD to the circuit board. You require a special tool to insert simultaneously into the slots on the bottom of the unit. The case must be popped open with equal pressure exerted by the tool at the two slots. The case must be prevented from popping off a distance longer than the wiring harness. Otherwise, the harness will tear away from the circuit board rendering the unit unrepairable.

I cannot use the GPS unit while in charge mode(NUVI 350)

Are you using a USB cable & charger to operate the GPS?

If so, you should stop and use the supplied cradle / power cord to power the GPS instead. The USB cable is used to transfer data to and from the GPS and on other models (maybe your 350, too) to slow charge the GPS battery when completely discharged. Powering with the USB cable will power up the GPS, but does not allow navigation, mapping, etc.

Press the Power button on the top right corner of the case.
If unit will not power on, battery may be dead. Try connecting car charger or power adapter to unit.
To charge battery faster, leave unit connected to power adapter or car cord. Press and hold Power button to turn unit off. Screen will show "Going into charge mode."

Nuvi 350 wont charge with car adaptor. But charges with ac charger in usb port of Nuvi. Any thoughts? I have another Nuvi 350 that does charge with this ones car adaptor.

Are you using the same port on the Nuvi to connect the car adapter and the ac charger, or two different ones? If not, then the jack could be broken (solder joint, pin?).

Garamin Nuvi 350...blanked out and won't turn back on.

Try the computer USB adapter. After it's been connected for about 20 seconds then try powering on the Nuvi. Even if your unit's battery is dead the USB connection should hold power on the unit so that the computer recognizes it as a Mass Storage Device (Windows). If that doesn't work then use the wall adapter and leave it plugged in for an hour or so. At that point if the unit fails to power on then push the reset button in the back under the antena and hold it in for 10 seconds while the cord is connected to the wall. This will clear any software related issues that would stop it from powering up - any other result indicates most likely a hardware failure. At least rule out your plugs.

Have you used the wall charger to fully charge the battery? If the battery is too low after lying around for a month it wil not start, giving it a couple of minutes of charging wo'nt help either, a good and full charge will!

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.
