Usually when it says External Power Lost, it has lost the signal between the power cord and the unit (the car was turned off while the unit was plugged into the socket and on or you pulled the plug out while the unit was on). If you are receiving this message and one of the above situations has not occured, you may have a problem with the cord, the fuse or the vehicle's power socket. Under what circumstances are you receiving this message?

It has a 12 volt power cable for the internal battery. Do you have the cable - refer to the owners manual (free download via the Garmin site) for more info. The internal battery is not normally replaced.

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.

I had the same problem. Found out that the fuse had blown in the power cord. I bought a new fuse from radio shack and have not had the low battery since.

Unit shuts off


I assume this message is when operating from the internal battery alone, correct? It could be that the unit is confused about the power source status... yes, electronics sometimes get confused too.

Have you tried a hardware RESET? The button is hidden behind the front panel, which snaps off by a fingernail slot located directly under the GARMIN logo on the front panel.

* Use caution removing and reinstalling the front panel... it's somewhat fragile... wiggle it a little to get it off.

Press where it says "Press to Reset", hold for a second or two. Charge the unit with the car cord or USB cable, then try to turn it on again.

Once you can get the unit to (hopefully) turn ON, you should run all updates (there may be several!) using Garmin's Webupdater. (Connect to computer with USB cable first.)

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.

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.
