    My c340 won't turn on. After the reset button is pushed, it will turn on for approximately one second, one time only, and then remain unresponsive after that. We do not use it often, and keep it charged, so hopefully it isn't a battery issue.

The reset button on my Garmin c340 is behind the plastic trim around the front. You will see a small indent for a fingernail or something like that along the inside at the top lift up at that point and it should come off no problem

There is usually a small hole somewhere on such units that lets you insert a paper clip or a pen to reset. It is often marked reset, but not always. Look for a round hole about 1mm diameter or less. On a Garmin such as yours it should be on the back. It might actualluy be to small for a paper clip, to you might try a safety pin or soething thinner. Make sure the hole isn't a speaker, as you might ruin it by putting a paperclip in. Also check your manual to see where the reset hole is located. It should state this in the trouble shooting section. My TomTom Go 700 has the reset hole on the mounting bracket on the underside.

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.

GPS StreetPilot c340 quit working

Plug charger in, and then reset it. Let it charge for awhile before tryng to use it though. It sounds like the battery is very very low. When it is plugged in it still will not operate unless the battery has some charge in it. I hope this helps.

Remove the face cover (GENTLY pry it loose by the fingernail groove directly under the GARMIN logo), press the RESET button, then re-attach front cover... this is covered in the owners manual, also available online at /support /downloads

Display problem

Have you tried resetting the unit? It sounds like you may have a problem that Garmin needs to address. I would try to reset it first, then make sure you have the latest firmware loaded on the unit. If you still have the problem, it may have to be sent to Garmin for repair.

Facing the GPS system, remove the front cover with your nail or something sharp and under it you will find a reset button. If needed, refer to page 30 in this manual (different model but same principle, see website below) for pictures:
