Garamin Nuvi 350...blanked out and won't turn back on.
I have a Garamin Nuvi 350. The unit turned itself off and won't turn back on. I've tried turning it on while it's plugged in and while it's not. It won't go back on. Any suggestions as to what may be wrong?

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.

For all those Garmin 350's that won't power up - I have one myself and here is what I did. Under the antenna flap there is a reset button. press it. It does not delete your favoriates or any recent trips but it does allow the 350 to power up! Try it, you can't lose!

try and get it plugged into a computer using a USB data cable, if the unit comes on most likely all you need to do is go to www.garmin.com and run a software update off the webupdater. and also try holding the power button for 50-60 seconds
I have the same problem with my Nuvi 350. It's only about 2 months old and the sound went. I turned it on the other day to use it and the sound did not sound right, it sounded like the speaker was blown. I turned it off and turned it back on and that was it, the sound was gone. I did everything possible and can't get the sound to come back. I called Garmin and now I have to send it in for repair. I looked around the web and noticed that Garmins have big issues with the sound going on the units. I hope they fix that issue.
Fixed it! Ok there are two tiny screws at top of the antenna that you can just barely see or get out.You've got to get them out first.Then I removed my antenna by applying a thin screw driver to the left side from rear view(near power button )and a black cam with a spring in the middle popped out. You may not have to remove the antenna itself -I don't remember-see if you can skip this step.Once the 2 screws are removed you can unsnap the unit. The screen portions two cables can be left plugged in, but you need to remove the antenna cable/connection at this point.A little black strip should be rotated upwards and the cable will come free, Later when putting back together place cable in assy and push down small black strip till it locks the cable in place again.Next remove the one large philips screw that holds down the board so you can pivot it forward. Once you get the board pivoted forward you'll see a small connector with red and black wires coming from the battery,all I did was disconnect it for 10 seconds or so,plugged it back in, pressed the power on button and after I did,the unit came back to life! I then very carefully put it back together and checked everything! so far so good! Good luck
Garmin released firmware version 4.40 to correct DST (daylight saving time in the United States) If your device firmware is 4.40 or later then it should correct once you turn the unit on it acquire a satellite lock.
If your unit firmware is earlier than 4.40 then you will have to update to the latest firmware from garmin site.
If you don't want to upgrade then reset your timezone to one that is an hour earlier. Or wait until April and it will change time by itself.
Have you downloaded the latest firmware for the unit? If not, download the Web Updater from Garmin and download the latest version. This may help. Also, make sure the antenna is fully extended while using the unit.
I have being having similar problem as every one else. There is nothing wrong with your Nuvi. Garmin (the company is the problem) they are trying to make you buy a new map--Not Exactly Cheap--Do Hard Reset and solve all the problems.
1) Place a finger (Any finger, middle finger worked for me!) at the left lower corner and turn on the Nuvi unit a message appear saying "Do you really want to start up in maintenance mode?" tap Yes 2) At the Maintenace screen tap clear user data (this will restore to factory condition) and follow the instruction on adjusting your prefered setings.
3) turn it off and Repeat step 1, this time when you get to maintance screen tap on "Clear waypoints" and follow the instruction. Let it sit for about an hour then voila.
