Need battery for the Nextar GPS model x3-02
Actually, it's quite easy to replace:
i. Take off four screws at the back.
ii. Between the body and the front bezel, insert a utility knife. The bezel is fixed to the body with tabs. I started from the left hand side from front. The tab is in the center. Careful not to scratch the bezel or the body. Once one tab is open, you can slide the knife or whatever tool you're using to open the rest. Be careful not to scratch.
iii. Once the front bezel comes off, you'll see that the touchscreen is held to the bezel with the help of four tabs. take the touchscreen off.
iv. Next, take the ribbon cable off from behind the screen. You'll have to flip the flap holding the cable open.
v. The screen is held to the main board with the help of a tape. Don't take it off. Take off three smaller screws which fasten the circuit board to the back body.
vi. Take the antenna off. It's quite easy. It's the same connector that is used for Blue-tooth or wireless antenna on laptops. It'll just flip off.
vii. Next, take the board off from the back plastic body. The circuit board will still be held to the back by two connectors, one (two wire, smaller one) connecting the circuit board to the speaker, and another (larger one, four wires) connecting it to the battery. Both the battery and the speaker are for now fixed to the back plastic body.
viii. Once you've done that, the battery is exposed. Take the battery off (held by two tapes, and some double sided sticky tape to the back body).
The battery is 35mmx55mmx5mm. Buy any 3.7v battery from ebay. That'll cost you about $10, including shipping. The only problem is that on ebay, you might not be able to buy the same connector. Most of the batteries that you get from there also have protection circuitry to protect against overcharging etc. So you'll only have to replace the connectory. For this, take apart the battery from top. Just peel off the green tape. That will expost the connections. Solder them off, and replace the entire chord on the new battery.
Sorry, I'm too depressed right now on account of loosing my job :-) Otherwise, I'd have included pics too. But I guess if you're not afraid to do DIY projects, you should be able to change the battery yourself. Quite easy.
