How to remove and change the battery in a Tom Tom GO 540 Live.

Answer: AnswerI 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.Not sure if this will help but they may be close designs
