How to Change the Battery in a Garmin Nuvi 760?

Postby S-Turner » Mon Jul 26, 2010 7:01 pm

I bought a Garmin nüvi 760 GPS about two years ago. You can read my “first impressions” review here. Not long after, I signed up for a Garmin nüMaps Lifetime North America Map Updates subscription. You can read about the installation process here.

Several months ago, I noticed that the battery life was getting a little short when it wasn’t being powered by the automobile. That’s not a big deal. About the only time I have it unplugged is it I hand it to a passenger to search for something. Still, I figured I’d replace the battery if it was cheap and easy.
The battery is part No. 361-00019-11

I kept putting off doing anything until someone posted a part number in the Garmin Nuvi 750-760-780 Group. He said, do a search for Part Number 361-00019-11.

BINGO. I ordered from the fine folks at BatteryShip.com. The battery was $19.95 with free shipping and a set of tools. I could have gotten a similar deal through Amazon for about a buck cheaper, but I would have paid $4.99 shipping.

1. Unscrew the back
Remove the two screws holding the back on. This is where you’ll be glad you ordered from someone who sends tools along with the battery. Those teeny-tiny screws aren’t Phillips screws. They use the T-8 Torx driver that was in the tool kit. I don’t think I had anything that small on the workbench.

2. Pry off the back cover

The plastic widget looks like a miniature version of a tire lever. The cover has a pretty snug fit, so the tool is helpful. Be firm, but gentle and it’ll finally come off. Be careful around the on-off power switch.

When the cover finally snaps off, don’t yank too hard. The speaker and battery are attached to the cover with some fairly short wires.

3. Unplug the blue and black speaker wires

The speaker wires are fairly short, so I unplugged those before the battery.

4. Unplug the old battery

The old battery is stuck to the back of the cover with two-sided tape. I saved the tape to put on the back of the new battery to keep it from moving around when I closed the case. When you’re sticking it down, the wires should be on the top, inside of the cover so they’ll reach the connection terminal.

6. Plug in the new battery

Unless you’re a big fan of brute force. It’ll be less frustrating, though, if you put the red wire on the left side instead of trying it with the green wire on the left.

The terminal for the speaker is the ivory-colored rectangular device in the middle of the frame. It’s keyed, too. I think the blue wire goes on the left, but I can’t swear to that. It’s a tiny connector on a short wire. If you have fat fingers, a pair of tweezers might be handy.

8. Pop the cover back on
Make sure you don’t have any wires trapped, pop the cover on, then replace the two screws. Life should be good.
