How do you replace battery in a garmin?

Answer 1

I have TomTom 910 in USA, (and I have one in the UK). Access to the battery is behind the front screen but the plug is under the circuit boards.

1) Remove 4 screws under ends of rubber strips on back. (All screws are Torx number 6)

2) Remove back cover. Front frame around screen comes off easier now.

3) Remove 2 screws in round top circuit board. Remove 4 screws from lower circuit board. These two boards may have a glue connection. Do not worry if it separates

4) Lay back circuit boards to unplug battery. Note flat ribbon cables are fragile. The 3 wire plug is the battery. Unplug wires to battery from receptacle on circuit board.

5) Remove front screen by pressing a screwdriver against the small metal tags that follow the edge of the screen. The tabs need to be pushed in slightly to allow you to lift the screen out. It may need some leverage, but be careful not to put the screwdriver to far behind the screen as there are a couple of thin cables for the connections.

6) To remove the hard drive you may need to unscrew the vertical black tags about 2 cm long. These simply come away and are grasping the business card size silver box IE the hard drive. The rubber end caps are pressed in, pry out with small screw driver.

7) Remove battery and replace. Note the two sided sticky tape around battery. When putting more tape on, be careful you do not put to much around the right hand end as it will connect with the thin cable when you put it all back together.

9) Reverse assembly. Mine works fine now, good luck. (and so does mine! BLP)

Footnotes: I did not have a Torx #6 screwdriver nor could I buy one locally. I found a #7 mini star bit works just fine. Source: Harbor Freight item # 93316, 6 piece Mini Star Bit Set - $3 PMVN - 9/19/2009

I am not advertising but Batteryship.com included with the battery #5 & #6 torx screwdrivers, a very small Philips (star), a straight screwdriver and a plastic pry tool. Whatever I paid more than another place it was worth it.

When disassembling do not remove the battery clip. Just pop out the battery from the front (experienced having to reassemble that whole thing). Also having a set of tweezers to put the electrical connections back together helped a bunch.

When changing the battery the ribbon cable from the circuit board to display has lost some of it connections at the connector. Easy to do when seperating the display from the circuit board...

Besure to unplug the battery before trying to re-seat the ribbon cable.

You are going to have to go back in and re-seat the the ribbon in the connector. There a a plastic white clamp that has to be slid forward toward the ribbon cable (away for the connector). Be very careful not to break it, It will only move about 1/16 of and inch. Use something like a metal dental pick to move it. Move the clamp from the two ends of the clamp not the center.

Then re-seat the cable keeping it perfectly straight in the connector, then while holding the ribbon in place slide the clamp back in place.

Plug the battery back in and test the gps out to make sure you got the cable plugged back in correctly. before re-assembling the case.

The LCD display end of the cable is soldered and usually does not create a problem.

I like placing a piece of mylar tape on the ribbon and circuit board at the connector to hold the ribbon in place.....
