The internal power connector has become loose and does not recharge the internal battery, I opened the unit and glued the connector back...''I tried soldering but it would not have it'' anyway I switched it on and got no power up at all, when I put it on charge there was no battery indicator on screen to indicate it was charging, I presume the hot shoe plate cable connector inside the unit has nothing to do with it, or do you think I should try and get it re-connected again? I have voided the warranty as I have opened it up myself...only having just getting it fixed because the same damn thing happened...any idea's anyone?

Re: Broken Power adapter
External power adapter? if you broke open the gps receiver and used any glue make sure you didnt coat the silver looking tiny metal parts or you just insulated them from the power adapter.. scrape off the glue gently with a small flat screwdriver. double check your wires to it the center conductor is usually white or red but the outer is ground or copper braid or black wire also check and make sure you didnt
solder splash short the connector. gently tug on both wires if they bust loose you need to resolder proper 60-40 rosin core.
adapter problems is easy . get a meter and check for voltage out from it should be like 14 if rated 12v. also you can just plug it up and trace to point where the voltage is lost to battery.

Here are a few tests you can do. Bear in mind if the unit has not been charged for some time and the internal battery is completely flat, you will need to leave the unit on charge for some time even to get a charge light from the LED. Leave it on charge for at least 2 hours.
First, check the LED is lit when the cable is plugged in to the cigarette lighter socket and/or mains charger? If it is not, the fuse in the cigarette lighter adapter may be faulty or the charger may not be working.
If the fthe LED is lit, then is power available at the end of the cable that connects to your unit? Use your DC voltmeter to check this. If no power is available here, then your cable/charger is faulty - obtain a new one.
If there is power at the connector, then the unit may be faulty.
The connectors are obvious, careful when youopen it up as the wires aren't very long! Look at the internal battery - it may be corroded looking - which is a sure sign it's gone west. Lots of info online on replacing it, you can try carefully snipping one of the battery leads and see if the sympton changes. Good luck
I had the same problem on a trip. Required two fixes and once I did this the unit worked fine.
1. Replace the fuse in the car adapter (reason it wasn't charging when I used it in the car).
2. See the users manual on page 31 regarding resetting your C340. http://www8.garmin.com/manuals/StreetPilotc340_OwnersManual.pdf
Solved:Opened the iQue and used
a heated knife to cut horizontally into the + pin and it comes like a
U, upside down, from the circuit board, and the exterior side of it was
broken. Used tiny plastic and sealant in the hollow space inside the
connector and soldered thin copper wire (used for exploding dynamite)
from the horizontal part towards the exterior.
I've got one that has a problem with the power connector. Look on the adapter thingy (has the female power socket along with the usb socket). With a pin, wiggle the center power pin. If it is loose, this is the problem. Carefully use a knife to open the adapter thingy (it's glued together). Go to Radio Shack/Fry's and get a replacement power female socket that solders to the little PC board in the adapter thingy. This will fix it.
Works great when it works. They are also know to freeze up. People have reported that it only works up to 6 months then it won't turn on. Even worse, tech support is few and far between and it seems nobody knows how to work on them. You can send it back to the manufacture to have it repaired under warranty, but don't look for it anytime soon. They will hold on to it for months. For me, I use a road map, It never stops working, and its always in the glovebox.
