Question about Garmin StreetPilot c340 GPS Receiver

1 Answer

I just received the Garmin C340 GPS as a gift from my daughter.

I want to know if I can plug the unit into my plug that says from 12V to 120V since your connector states it is 250V? Can't find anything in the package to tell me about this.

Only use Garmin approved power connector either AC or DC (cigarette lighter adapter), otherwise you risk ruining your unit. The DC power adapter actually step down the voltage from 12vdc to 5vdc. Using anything other than a Garmin approved adapter can fried the unit.

Most likely they will request a proof of purchase to confirm you are within their limited warranty policy. You could try saying it was a gift? Might work around holiday season.

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 gps battery says low battery and shuts off when I set it down after putting in travel info. What to do ?

Check the power on your 12v car cord. The internal batteries are low and are not being charged by your vehicle system. The fuse may be burned out in the 12v car plug.

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.

Garmin 1412, wont run on battery power, DC only. Need info on maybe a full reset whether to return as defective

I found there are select 120v AC adapters that will work on Magellan GPS. When a working 120v or 12v adapter to mini USB adapter is plugged into the unit, the battery bars will be 'scrolling' and therefore charging.

When your adapter, or even USB cable from your computer, is plugged into the GPS unit, and the battery goes to FULL, it is NOT CHARGING. The battery bars must be SCROLLING for the unit to charge. In this case, get a different adapter until it works.

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. .
