Re: how to replace internal battery

Remove the Front facia surround Undo four screws holding internal works to outside body You will need a T6 star screwdriver for this. Remove internal works from body at the base you will see silver foil covering feel over this you will find 4 T5 star screws securing this remove these and also remove speaker by two locating T8 star screws. Gently remove the electronic board keep all locating cables intact You will then see two T4 star screws holding battery holder remove these and the plastic holder .Unclip battery and disconnect from Pcb Board fit new battery and reassemble. .

Replace battery on my om tom go 300

original battery ICR18650-24 sometimes marked Type VF5 or similar. Battery

  • Remove the front screen surround -- just gently prying does the trick. (Img 1)
  • Undo four T8 screws holding internal works to outside body. (Img 2)
  • Remove internal works from body. There is a cover/clip for the bottom panel (where the car mount connects) that just falls out once the insides come out -- pay attention to how it fits in, so that it can be replaced on reassembly.
  • At the base you will see silver foil covering (Img 5), the foil needs to be peeled back in places, but I left as much of it on as possible (unlike the images I'm referencing).
  • Peel back the foil around the speaker, and remove the two T8 screws, being careful not to disconnect the speaker -- it only needs to be moved aside. (Img 6)
  • Continue peeling back the foil down to the circuit board, but leave the board itself covered. You will need to manipulate, but not remove, the thin metal "cage" that is shown removed and behind the unit in Img 11.
  • On the still-covered circuit board there are four T6 screws that need to be removed. These screws can be seen in Image 11 -- one on either edge at the bottom, and one on either side of the car mount in the middle top.
  • With the foil loosened and the screws removed, manipulate the metal "cage" to expose the two T6 screws securing the black plastic battery holder (plainly visible in Img 11). Be very careful not to accidentally disconnect any of the wires/cables.
  • Remove the battery holder, unclip the old battery, replace with new one, and reassemble. (Img 16)
  • The unit should be able to power up as soon as the new battery is connected, so I tested it a few times as I reassembled, just to be sure I hadn't jostled anything loose as I went along.

I bought the new maps from website, and can not install

If the software crashed whilst updating, you will find that if you try to restore from a complete backup when you switch on next time it will either say you cant use the map or will just freeze, fix re format both the internal memory and the memory card, then find where tom tom home had stored the files, then using windows copy the contents from the 2 folders back into the relitive internal and external card, you will then find that you will get the mesage that you cant use the map, this is because tom tom home doesent always put the map data into the correct folder, to fix this find the licence data and the map data that has been stored on the sd card instead of the internal memory and copy it into the internal memory, before switching off press the reset button, when you switch on you should find that you have a working tom tom
