Won't Charge I've rarely used the PiN570 since it was given to me as a gift 3 years ago. I recently found a use for it, but now it won't charge. It works when it's plugged in, but the indicator lamps have no light and it doesn't charge at all. As soon as I unplug it from the charger it dies completely. I also tried the car charger with the same result, it provides power but the unit doesn't charge. I'm guessing this is probably a battery issue, but wondered if somebody had the same issue. I don't know that it's the charging port since the unit gets power when plugged in. Thanks, Jake

You need to change the battery. It is not a fun thing to do. Do a word search for Navman PIn 570 Replacement battery either on Google or Ebay. You have to disassemble the unit to get to the battery that is taped to the unit's motherboard. There are hidden screws on the back of the unit, then you have to gently pry the 2 halves off. Big Heads up here: the round dial on the left side...be sure to tape that in place when you first disassemble the unit, otherwise it falls out into 2 or three pieces...that dial is a pain to get back together if you do not tape it.

I recently replaced the battery on my unit. There are two additional screws on the back of the unit, near the bottom in addition 2 screws under the flip up antenna. They are covered by small black plastic discs which need to be pried off first. After removing the rear cover with a knife edge (or similar) there are several other screws which attach the circuit board to the front of the unit which need to be removed. Note that the one near the edge should only be loosened, and the board slid out sideways. Once this has been done you should be able to access the battery which needs to be pried off the board, as it is attached with an adhesive patch.


(If the battery is totally dead it takes about a day before the charge led starts flashing.)
