Had the same problem, there is a solution, Lowrance has a series of problem fixes by reseting the unit. I found it by e-mailind Lowrance and they gave me the web site. Sorry i can't remember what keys you hold, but it was simple and it worked.

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 c340 loses the satellite very frequently. Battery?


1. make sure the unit is as low un the windshield as possible, remember it needs to see the sky, the more sky it can see the more sat it can lock in on.
2. Check the GPS Mode, under tools(Wrench), select system, the GPS mode, make sure it is in the normal setting. WAAS is more accurate, but most of the sats are at the equator, so in some areas the coverage is not as good.
Hope this helps.

Why does my garmin c340 tell the wrong side of road a house is on?


This is common with most GPS receivers not just yours. It has to do with your position relative to the Sat. and the amount of processor utilization looking for triangulation readings. Basically its a brief signal deterioration on one or more signals so your device is lagging a bit.

please rate. thanks.

Use MapSource to transfer the Waypoints from the unit to your PC. If you lose them, you can then transfer them back. (I updated a C330 from 4.40 to 6.10 and did NOT lose them, however.)

Garmin C340 startup


The clue is that the voice is slowing and low pitch. The main processor time base has slowed... which means everything will be buggy.

First try would be to Reset the unit. Remove the face cover (GENTLY pry it loose by the fingernail groove directly under the GARMIN logo), press the RESET button, then reattach front cover... this is covered in the owners manual, available online.
If not, then it sounds like a hardware failure... time for a 1-800-800-1020 call (their customer service number)
