    I found my volume wheel with the trimmer pot inside the unit. The three legs had sheared off at the printed circuit board. The label on the pot is 103B. Any idea where to get a replacement?

I had the same issue. My C340 fell of the dash and the volume control (potentiometer) broke off and was rattling inside the case. I tried to find a replacement (103B stamped on the pot) but have not been able to find one. I tried a mini 10K ohm pot from Radio Shack, but the posts were not properly positioned for the circuit board inside the Garmin.

I took the easy way (for now) and simply strapped the two control points together with a piece of wire giving me maximum volume. Orient the circuit board with the missing volume control to at the bottom right. The control mounts with 5 points, two on the right edge of the board are simply physical mounts. There are three other connection points just to the left in a slight arc. The top and bottom point have holes to place the legs of the pot. The broken off legs may still be in these holes. Solder a piece of wire between the top and bottom points. Be careful since the solder pads (to the left of the holes are very delicate.

Not an elegant filx, but you get the voice back.

Try charging it from the WALL charger. The battery inside the unit may not be too great. Try it - over night from the WALL charge -not the PC charger. 8de415c.jpg

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
nstructions
  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.

Garmin GPS not switching on


If the reset described by justaskjoe doesn't help, then check the power cord. There's a fuse inside the power plug, held in by a screw ring which is notorious for coming loose. Make sure the fuse and spring are in place and the ring is screwed on firmly. My daughter's C340 stopped working because that ring came loose and the fuse fell out. Also remove the unit from its mounting cradle and snap it back in to ensure good contact.

My Garmin C340 is dead!!!!


I had the same problem on a trip. Required two fixes and once I did this the unit worked fine.
1. Replace the fuse in the car adapter (reason it wasn't charging when I used it in the car).
2. See the users manual on page 31 regarding resetting your C340.

GPS has no sound.


The screws are hidden behind the front faceplate.

The faceplate snaps off by a fingernail slot located directly below the GARMIN logo on the front panel.

* Use caution removing and reinstalling the front panel... it's somewhat fragile... wiggle it a little to get it off.
