Re: garmin streetpilot c340

It sounds as if the battery may be defective. I would contact Garmin and they can assist you in getting a new battery installed.

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

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.)

No.......the C340 STREET PILOT has a hidden reset button. Put your fingernail in the slot just under the GARMIN name on the front face plate. Gently pull the face plate outward. Don't take it all the way off. The reset button is on the right side of the front screen just under this plate. Use a pointed object and hold the button IN for 3 seconds and unit will turn off. When you power it back up it will REBOOT.

Garmin Street pilot C340 has always worked. This morning it did not turn on. I relpaced the fuse in cord. Any other ideas?

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
  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 has won't turn on, screen is completly dark unit is charged

I has the same problem with a streetpilot 540.. It wouldn't turn on, even once charged. There was no reset button under the serial number. However, prise off the grey plastic square plate on the front panel which goes around the screen. ( there's even a little space for your fingernail under the Garmin logo). The reset button is under that plate. Press that with a screwdriver then turn on. My unit turned on once reset.

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.

Dead Garmin StreetPilot c340

The battery usually has a small charge when arriving from the factory, but it can die before it is received. You should charge this by plugging it into the car or the computer.

Charging unit with AC adapter

I have a 100v A/C power / charger unit for my garmin C340 GPS that I use to charge my Garmin's battery every day. I can use thj adapter to run the GPS, or just turn it off and let it charge the GPS. But it connects dirctly to the Garmin GPS unit, not to the cradle like the Cigarrette lighter unit does. .
