Question about Garmin StreetPilot c340 GPS Receiver

StreetPilot c340 will not come on even when plugged in

Recently my Garmin c340 "died" on me. When plugged in to a cig. lighter that works or a power outlet in my truck, it will not come on using the "on" button on the lower right side. I tried a different power source today (diff. car) and the initial Garmin screen came on for about 2 or 3 seconds. All I know is that the power sources are good. Where is the reset button located? Where is the fuse located? Where can one buy a new fuse, Radioshack? Thanks in advance.

    I have the same issue. The unit was working fine, the battery was running low and then the unit went blank. I'm not able to power it up or charge it using my computer or the cradle in the car.

    I can not get my garmin to turn on and stay charged. We took it to Florida but when removing it from our rental, the place at the bottom of the screen where you plug in the charger cord, came off. It will now not stay attached. What can I do?

    Thank you. We love my Garmin and do not wish to buy another one.

    I have a similar problem with the Garmin C340 that I use on my motorcycle. Recently it has started to turn on and boot-up OK, but then the screen goes black and the unit simply turns off. Even when drawing power from the motorcycle's battery, the unit simply turns off. The internal rechargeable battery level appears to be around 25% charged. After I followed the advice given here about using the Reset button under the front cover, the unit appears to be back to normal. Thanks for the tip!

I had this problem before, i called garmin and they told me that the charger cradle was not design properly so it sometimes doesnt charge...anyways...carefully remove the grey cover around touchscreen and there is a master reset which will set it back to worked for me...good luck!

Where you plug in to charge is broke


If you broke the lighter socket on car dash, replace it.

If you broke the cable replace the cable. Here the spare:Garmin Power Cables

If you instead damaged the power socket on your Garmin, call the Garmin number listed in the owners manual. The Sat Nav must be sent to Garmin for repair:Garmin ' Contact

Next time use a Suction Mount Windscreen Holder

Garmin will not charge using car charger. The fuse is intact. It will charge using usb port per computer. Any ideas?

meter out the cable and see if you are getting anything out of the car charger, of course while the car is running. If you are getting no juice, then either the fuse for the cig lighter is bad or the car adapter is bad. either way, easy fix. Good luck!

Garmin C340 battery not charging

The Garmin batteries tend to die after about 2 years. Garmin will replace the battery for you but prepare to pay top dollar. It is a shame because the problem is commonplace. They should have made the replacement user friendly. The battery is buried deep inside and it is soldered.

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. .

My garmin c340, only a few months old just died--cannot get it to turn on and it definitely is not the fuse. Help!!

I took the faceplate off very gently starting under "garmin". I plugged it into the cig lighter in my car and turned my car on. I pressed the reset button and it turned on (THANK GOD!!). I then let it charge a little.

Garmin c340 went black and can't get it working

The battery was completely dead. I must not have had the cord plugged in to my lighter, or maybe it wasn't sitting properly on the cradle, and it was running on battery power. I found that when I charged it by the computer, it was ok. It is working with no problems, now.

Karen died

If the unit works on battery but not the AC adapter or cigarette lighter adapter, obviously the problem is in the adapter.

1. Have you verified that you have +12VDC at your accessory jack?

2. Have you checked the fuse in the cigarette adapter?

What are you powering it with when not on the battery?

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

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.

Garmin c340 gps freezes up

Avoid buying Garmin GPS. Their units have a non user replaceable battery that last about 2 years. After that, you have to send the unit to Garmin to replace the battery and be hit with at least $150 plus shipping. Possibly more if they need to fine tune something else. Look at other brands with easier battery replacement such as Sony, Navigon, etc. Garmin is a total rip off.
