Replacing the nuvi 350's battery is actually not all that hard as this video demonstrates:
The company that produced the video sells a kit which includes the battery and tools necessary to do this yourself if you'd like. See: I swapped the battery of a friend's dying GPS using the aforementioned kit and all went well. His nuvi 350 is back up and running smoothly.

I contacted Garmin about this problem .. this is an answer ...

Thank you for contacting Garmin International.

I'd be happy to assist you with this. Connect the unit to a computer via USB cable and if it powers on follow the steps below:

1.Log onto GARMIN.COM
2.Rest your mouse on the word SUPPORT in the black banner that runs the length of the page
5.Click on Step 1: DOWNLOAD and install WebUpdater
6.Depending on your operating software choose one of the following
-If running legacy Windows (Pre 2000) click the 1st DOWNLOAD
-If using a MAC click the 2nd DOWNLOAD
-If running Windows (post 20000) click the 3rd DOWNLOAD
7.Scroll down and AGREE to the terms

NOTE: Once the program is installed it will say “WELCOME TO THE WEBUPDATER WIZARD”.

Once this is done the program will say the following, "PLEASE CLICK NEXT TO CHECK FOR ADDITIONAL UPDATES"

10. Click next
11. You'll want to place a check next to anything that says SOFTWARE or FIRMWARE
12. You can also scroll through the different vehicles, texts, and voices and choose any you wish

Once this is done this program will be on your computer and you should check it at least once a month for additional updates.

Leave the unit connected to the computer for 3 hours to obtain a full charge on the battery

The battery on this unit was not designed to be replaced by the consumer. Your best bet would be to contact Garmin.

Nuvi 350 System Software Missing

If you have a nuvi 350 download the software to your computer and then load the software onto a formatted sd card. Insert the sd card and bootup the Nuvi 350. The sofware will then load onto the Nuvi 350. If you have a Nuvi 200 I would think it works the same but I have not tried it.
Hope this helps

Nuvi 350 will come on but will not stay on

The internal batteries are not user replaceable. Please don't try to do this yourself. I've received numerous emails from people who have destroyed the Nuvi attempting to do this. I have replaced numerous Nuvi batteries. The life of the battery depends on how many cycles its gone through.

Garmin nuvi 350 battery replacement

I can't do it for you, but I have done it myself. See the instructions on my webpage at Pictures and everything, along with where I got my battery and the part number, etc. Warning, there are many opportunities to damage your unit doing this. Not for the novice.

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.
