Instruction for replacing the battery for a Gamin c330 GPS, suggest removing four screws on the c330. No screws are visable? Any ideas?

The battery is located inside the GPS but is not readily accessible.
The unit must be disassembled in order to access the rechargeable Li-Ion battery. To disassemble the unit, the decorative border around the screen must be peeled off (It is held on with adhesive). Once removed it should expose the screws that hold the plastic enclosure together. Garmin StreetPilot c330 Battery Replacement

Hi

You can indeed replace the battery for this unit. There are four black screws to remove to seperate the case. Garmin charge up to $150 for an original battery - however see link below for information on what the battery looks like and you can order the battery from this company for around $25.

Hope this helps.

Since you're posting here, I'm assuming you have a C330.

Step 1 remove face plate.

Step 2, remove 4 screws.

Step 3, pull gently apart and take note of the antenna that's on the top of the garmin unit. It comes out easily so you must make note of it's orientation or you may never get the unit back together.

When apart, there are two screws holding the battery.

Battery plug must be cut and new battery spliced in.

Battery can be purchased on Ebay. If you can't find it, do a search for tom tom. They use the same battery.

Yes...... but keep in mind, it's not easy.
Step 1 remove the face.

Step 2, remove the screws. There are 4, one in each corner

Step 3, The hardest part. You can pull the unit apart with ease, but I must stress, keep note of the antenna which is at the top of the Garmin unit. Slightly open the unit like a hing with the top being the hing so you can take note of the antenna and how it sits. If you don't pay attention, you may not be able to put the unit back together.

Once you make the necessary notes, the unit comes apart as you can see here. There are two screws holding the battery.

The only problem here is that the plug housing the wires to the battery also hold the wiring to the Garmin speakers. Even though you can remove the plug, you will need to splice in the new battery. You can get these on Ebay.

Pry off the colored faceplate around the screen. Underneath will be four screws. Remove them and open the unit up. You should be abe to access the inside of the unit to figure out a way to reattatch the connector. I have not had to do this but I have opened a couple up to replace displays. The hardest thing is getting the thing back together due to how the antenna mounts (poorly). Just open it slowly and visualize how it goes back in. I have no advice on actually fixing your issue, just on how to get in to look around.

The silver faceplate snaps off (there is a tab at the top of the screen); remove the silver faceplate, remove the 4 screws to open the unit. The battery is located on the back half, and is conected to the circuit cards with a balck and red wire through a small connector that also as two brown and white wires for the speakers.

After you remove the bezel on the front you will see 4 small phillips head screws, remove those.... While opening, pay close attention to how the built in antenna comes out, it will make it easier when putting it back together,

Did you try to perform a map upgrade to 2008? Turn on the Garmin and from the main menu touch the wrench,
then press Map, then look for Map info.


This will show the the current map version installed
