Garmin 760 not charging or working from the car charger. I changed the fuse and the green light is on but will not power up. It use to automatically come on when the car started and turn off but now, nothing. I can manually turn on the unit once I charge it in the house but the charge doesn't last long.

Hello,

Your units powered cradle has probably died out, this is very common with the 7xx series, see if you have a friend or someone that has the 7xx cradle you could try. But it is a very common issue, if you do need a replacement one can be obtained from here http://www.gpscity.ca/garmin-nuvi-700-series-cradle-replacement.html

Hope this helps!

The fuse may be gone in the charger. There's a ring, near the silver tip, of the plug that goes into the cigarette lighter. If you unscrew the ring the plug will come apart. Take care not to lose the silver tip as it may fall out. Replace the fuse and it may solve the problem.

The problem sounds very similar to what I have experinced on several occasions with my wife's 765T. It has to do with a poorly designed cradle.
I have gone through 3 so far under warranty. Now it has happened again and I am out od waarranty. Depending on the cost, I may just get another unit.

It's most likely that the fuse has blown in the charger plug. Instructions complete with pictures are available from http://www.garmin.com/garmin/cms/cache/offonce/us/support/searchsupport;jsessionid=DB06036F1F1FBB6DE01E21EE59D70192

what is the GPS doing, sounds like you need to replace the battery based on the symptom

hi,

1st of all let me say im on my 3 cradle now for my 760 because the connection inside the cradle where it mounts to the board is pretty poor.

since you said the traffic/charger has the green light lite, that means the charging part of it is working.

you can verify if its the cradle or the connection on the bottom of the gps where the cradle mounts by using the usb cable supplied with your garmin.

plug it in for a while, then check the battery meter after you unplug it..if its charging, the meter would have risen beyond what it was before you tried to charge it. the same can be done with a regular garmin charger (the one that uses the usb connection for the car charger to charge it)

broken wire or bad fuse. it may "look" good but actually be bad

Try holding the power slide to the left and holding it there for 8 seconds. If that doesn't work, try charging it via your PC & USB cable. If that doesn't work, try a mains charger if you have one (I had to do this with mine). Good luck!

Sounds like you both have a battery problem. I experienced a similar problem when trying to charge via the USB-cable connected to my computer.
Ended up buying an original charger (expensive) and the charging went smooth.
The car charger should in any case work fine, so probably your battery is not very healthy.

Try holding your finger on the battery symbol for about 10 sec. The unit will then switch to a technical page. There you can observe the battery and charging voltage. When I plug in my computer USB-cable, I read around 4,4V and that is not sufficient for charging my battery.
When connected to the original charger, this voltage rises to about 5V which gives a nice charge. When unplugging charger, the unit displays the battery capacity. If the charging voltage is OK, but battery capacity drops quickly after you unplug charger cable, the battery is probably bad. (Of course you have to charge is for some time) I think around 4V battery voltage give 100% capacity. 3,9V gives about 90% capacity.
This will not solve your problem, but can give you an idea about what is wrong.
Good luck.

Hi,

Slide the power key to the left 10 seconds.

Update at Garmin.com/webupdater

Jack to Computer and run.

your Software/data is safe.

check fuse in the end of the adapter

Regards.
