Forget it the charging socket/circuit is stuffed!
Did the same as suggested and also brought a new battery but no good.
I "hard wired" it so it has now a GPS only.
What a stupid plug they came up with (so much for supporting Kiwi made)
The amount of stress that is placed on the plug while its pllugged in and your driving,something has to give sooner or later.
Maybe there is a flat or stuffed lithium battery or battery charging circuit in the pin 570. fix: leave unit to charge for 24 h if
the battery still dosnt charge because it is over discharged, then you
may be able to push some charge in it after the battery is unplugged,
after opening the case, and removing the circuit board

I had the same problem, took the thing apart and checked voltages with a multi meter the battery voltage was 1.5 volts checked all connections nothing wrong put it back together" no go" held the reset button for over a minute, lovely green flashing light! hope it works for you
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.)
These sockets are on sale if you google enough. Ebay seller totalviews for example. Check its the right socket and be prepared for very small presise soldering. when you open the case, take great care not to break/dismantle the rocker switch that protrudes as it has minute elements in it. If charging is a problem but the socket appears sound,m check the plug that goes into it and ensure the springs go in and out to hold it in place.F4therchristmas
