My Nuvi 780 will not charge with the car charger. It uses the larger end and not a USB end. When you plug in any USB charger, it acts like it's plugged into a PC for updates and the navigation won't work. It does charge, but it is extremely slow and the charge is very short lived. I can't seem to find a charger for it. Any suggestions?
A couple part answer here. The USB pin out for the Garmin is strange. If it goes into PC mode, then the cable is got the wrong pin out for the unit. Try different cables until one works.
If you can get a full charge on the unit and the battery does not provide at least an hour + of battery use, then the battery needs to be replaced. Amazon sells replacement battery kits with instructions. You just have to make sure you order the right one.

This is the problem with the Nuvi 2xx series... the charging port connector on the rear is weak and eventually the connections fail. It does not have a quick disconnect port like the Nuvi 3xx, 6xx or 7xx series.
The connector has to be either resoldered or replaced. The bad connections are whats causing the problem, making your Nuvi think its connected to a PC rather than a true charging power source.

First make sure you have a Garmin CHARGER.
If the device does not power on it could be a result of a extremely low
battery. Please ensure that the device is receiving a charge while it is
connected to the vehicle power cable. If the battery is receiving power from
the vehicle power cable then the battery icon (located next to the time) would
disappear from the Main Menu.
If the unit does not power on while attached to the vehicle power cable
please follow steps from below to perform a soft reset:
The device should power on.
Notes:
SURE:
After installing WebUpdater once from the Garmin
website, perform all future software updates from your computer. Simply connect
your compatible Garmin device to your computer, then run WebUpdater from your
computer's "Start Menu" by selecting "Start",
"Programs", "Garmin", and finally "WebUpdater"
REMEMBER: It takes hours to
do a complete a map update.
Unless you bought the Lifetime maps you may have to pay for current maps.
Does this help? Let us know. Thanks.

Make sure you have the rite charger. Garmin will only work with a garmin charger. You may have accidently picked up a blackberry charger or something. Hope this helps

You have a short in the wire that runs to your unit. Other than holding the wire in the exact location until your charge is complete you would be better off replacing the charging cord. They should be available at your local shop for around $19-$29.00.
