Re: screen

No, there is nothing wrong with your screen. The unit automatically zooms in and out depending on how far you are from where you need to make your next turn/change in direction. It cannot be "corrected", this is the way the unit is designed.

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.

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:
