SOURCE: Battery replacement

Sorry I don't have any diagrams, but I'll try to give you what I did step-by-step and hope it helps you. First, if you don't already own a set of miniture screwdrivers, buy a set at WalMart. They cost less than $10. Get a small ZipLock bag to keep all the parts you are going to take off your GPS until reassembly time.
1. With a very small flat screw driver, pry off the gray/silver from around the touch pad on the front of the unit.
2. Under this cover you will find four Phillips head screws (the ones with the X on the tip). Remove the four screws and put them in the bag along with the frame you took off. This will allow the front part and the rear part of the GPS to separate. You may need to pry the two apart using a small flat screwdriver.
3. Once it's open you will see the battery in the rear of the case. It is about the size of a roll of quarters.
There are two very small screws holding down a silver color battery holder. Remove these and put both of them in the bag. If you have a digital camera, this is the best time to take a picture or two of the inside of the GPS. This will simplify reassembly later.
4. You will see several wires going from the battery to a white plug on a circuit board. Pull this plug straight up using your fingers or a pair of tweezers. Most of the connections to the battery have just been severed.
5. There are now four wires still connected, two to each of the speakers in the case. Now you have to decide how to break these connections so that you can reconnect them to the new battery when it is installed. You can either heat up the solder holding these wires to the speakers, or you can clip the wires. I tried the former but settled for the latter. If you do choose to clip them, do so as close to the old battery as you can so that you have some extra wire. Most likely you will need it.
6. The battery is now held in place only by some double-sided tape, so you can gently pull it out of the case.
7. The replacement battery will have the same white plug and the same color wires going to each of the two speakers.
8. Before installing the new battery, strip a small amount of the insulation from each wire end that is to be rejoined (8 altogether). These are the four loose wires on the new battery and the four still attached to the speakers. These wires are very thin and can break easily while stripping the ends. You will probably break most of these wires at least once with stipping the ends. That's why we left ourselves some extra wire.
9. Twist each of the stripped wire ends to its mate which is still attached to the speakers. Note that two of the ends are shorter and two are longer. Make sure the two shorter wires are connected to the same speaker and the two longer wires are attached to the speaker on the other side.
10. You are now more than half way done! Take a small piece of black electrical tape if you have some and secure each connection by wrapping the tape around where you twisted each pair of wires. If you don't have any or don't know what I'm talking about, you can use Scotch tape instead. If you are competent with a soldering iron, you can solder tje ends together instead, but it's really not necessary as long as each pair of joined ends stays together.
11. Next, place the new battery in the metal holder. The battery end where the wires come out should be toward the side of the GPS where the two shorter wires are located.
12. Holding the metal battery holder around the battery, reinstall the two smallest screws through the holes in the holder.
13. Plug the new white connector back into its socket on the circuit board. Note that this will only go in one way. You need to look for the tabs on the ends of the white plug and align them with the slots on the end of the socket.
14. Tuck the wires back inside the bottom of the case, then carefully place the two parts of the case together. You may need to try this part of the reassembly several times unless you have someoone who can help you. It really does help to have more than two hands.
15. Reinstall the four black Phillips head screws in their holes. The two parts of the case should be securely joined after you do this.
16. Finally, snap the gray/silver frame back into place and you are DONE!

Hope this helped you.

Why does my c340 keep losing satellite reception

Hello there:
please follow these instruction and this should help if not let me know and i willcontinue to get you more information for you
  1. Step 1 Calibrate the screen of the Garmin StreetPilot C340. If the touch screen does not seem to respond when you hit it with your finger or a stylus, you may need to calibrate it. To do this, turn the unit off and then hold down the "Power" key for approximately one minute. You will see a calibration screen come up that will recalibrate the GPS2_bing.gif unit.
  2. Step 2 Reset the Garmin StreetPilot C340. If your GPS unit is not responding or is stuck on a particular screen, it may need to be reset in order to operate. To reset, remove the face plate of the unit by gently prying it off. Locate the "Reset" button under the face plate and press down in order to restart the device.
  3. Step 3 Change the fuse of the Garmin StreetPilot C340. If the fuse blows on the GPS, you will need to make a replacement using an ACG/3AG 2 amp fuse. Unscrew the adapter cord at the end and remove the fuse found there. Put in the new fuse to see if this returns function to the unit.
  4. Step 4 Update the software for your Garmin StreetPilot C340. If the GPS is not providing you with correct directional information, you may need to update the software or download new maps onto the device. Connect the Garmin StreetPilot C340 with the USB cord to your PC and log on the Garmin website for available updates.

My Garmin C340 froze up. can't shut off and touch screen does not

Have you tried a hard reset? Take off the silver trim ring around the screen by hooking a fingernail under it above the screen and lifting it off. There's a reset button at the side of the screen. Press that for a few seconds and it should re-boot the unit.
