Another page with instructions

I posted this on GpsPasSion. Immediately afterwards someone posted this page which is cleaner and more concise than mine. You should look at both before starting your replacement. Use whichever one you like better. Or use both.

Symptoms

When I turned the car off, the screen just went blank instead of warning it was shutting down. When on, a voice prompt would cause a re-boot. Sometimes it would not power back on properly after a fast shutdown. After replacing the battery, everything works like it did before.

Tools needed:

Torx driver - size T-5
Phillips head screw driver - Size 000
Small flathead screwdriver or pen knife for prying and for sliding the springloaded catch.

I got my battery at Batteries Plus (see photos at the bottom of this page).

Their order number appears to be GPS10021, unless that is some generic part number for special orders.
The package and battery has no manufacturer listed, but says it's a model PDA-201LI, part number 361-00019-02 (Same as the Garmin part number) with an additional number: IA2B309C4B32
Both are 1250mAh - 3.7v. The plug fit perfectly, so I am confident it is the right one.

Warning

This is not an easy disassembly. There are many opportunities to damage your GPS receiver, including small delicate ribbon cables and little plastic tabs.
If you use this page for instructions, you do so completely at you own risk!!!.

The photos have two different appearances (size, color balance) because I started with my digital camera, but since it couldn't get the closeups, I then went back and took a few more with the 35mm and extension tubes.


Click for large	This is the Garmin Nuvi 350.	Click for large	You can confirm this by looking at the sticker on the back that has the model number on it. I'm guessing the NA means it is a North America version.
Click for large	Open the antenna, put the Nuvi face down and remove the two little screws at the top of the antenna. (This requires a T-5 torx driver). Be sure to take this slow and enjoy it, because it is about the only part of this disassembly that is easy. (For re-assembly, these are the short torx screws.)
Click for large	Warning Look at the large version of this photo to make sure you know where this tab is so you don't break it. This photo is out of sequence in the disassembly, but you need to take a close look at this in the large view. There is a little tab that sticks out to the right on the inner cover. This tab is the reason you must remove with a twisting motion as shown in the following photos.	Click for large	Here you can see how the two pieces fit together.
Click for large	I have included several photos just to make sure you understand how the pieces fit together.	Click for large

Click for large	Also, before you start, these photos show how the antenna wire fits into the slot on the back piece. This is why you have to twist, to get the wire up out of that slot. But don't twist too far or you might break the little tab.	Click for large
Click for large	These two photos show how you gently twist the cover up.	Click for large	You can now see the black sleave that covers the ribon cable for the antenna. This fits in the rounded end of the antenna cover.
Click for large		Click for large	Sorry, bad shot. But you can just barely make out the tab I was warning you about as I am just starting to remove the cover.
Click for large		Click for large	If you pull on the antenna, the ribbon cable will pull out of the sleave. It is spiraled up in there so it has a lot more slack than it looks like.
Click for large	OK, so still no way to get the antenna off. But wait...	Click for large	Sorry, another bad photo. On the right side of the rounded bottom is the cavity the antenna wire goes. On the left is a raised portion. There are two slits in this. Put a knife point or a very small flat-head screwdriver in this slit and push the spring loaded catch to the right. Then push the right corner of the antenna down towards the center of the GPS.
Click for large	Here is a shot I took after disassembly. On the left you can see the cavity that the antenna wire rests in. On the right, you can see the little slots. To push the spring loaded pin back, use the slot on the right.	Click for large	This little plastic piece, along with a very tiny spring, will then pop out.
Click for large	Here's a little better shot of the plastic piece and the spring.	Click for large	Here you can see the socket the plastic piece rests in to give that click-stop motion when you move the antenna during operation.

Click for large	Finally, we have exposed the two little screws so now we can actually take the case apart. These are also T-5 torx. (For re-assembly, these are the long torx screws.)	Click for large	I found the cover made a good place to collect the mounting number of little bits I didn't want to lose.
Click for large	Work a knife, then a small screwdriver around the case. Don't try to open it until you have it loose all the way around.	Click for large	Be very careful to not open it up too far so you don't strain the ribbon cable to the display. Where the ribbon cable goes into the circuit board, towards the bottom edge to the left (left in this photo, that is), there is a phillips head screw that must be removed. I used a size 000 for this.
Click for large	This was during reassembly (with the new battery) but it's a better shot of where the screw is located.
Click for large	Once you have the circuit board loose, pry the battery out (It is glued to the case), then find the tiny connector and disconnect the battery.	Click for large	Hey, how 'bout that. It's out.
Click for large	For reassembly, the plug will only go in one way. Don't try to force it. On mine it went it extremely easy when I had it right. Disconcertingly, though, it does not seem to click-lock into place. I hope it stays.	Click for large	If you look very close, you can see the pin holes towards the bottom. In the photo to the left you can see the pins are at the top. The plug as shown here would need to be twisted upside down to fit the socket in the photo on the left.
Click for large	The battery came. Here's the package in case any of the numbers help you find yours.	Click for large	I got mine from Batteries Plus. Again, maybe the numbers will help.
Click for large	Old Battery.	Click for large	New Battery.
Click for large	Notes for re-assembly: The phillips head screw holds the circuit board in the case. The long torx screws hold the case together. The short torx screws hold the antenna together. Put the spring in the plastic piece before inserting it into the antenna.
