I have to move the connection cord at the unit. could it be the connector to the GPS and how can it be repaired????
@can77 , Carlos, you should try another charger if possible to rule out the charge cable end/plug being the problem. I am pretty sure the charge port will be soldered to the logic board and if loose,you may be able to or have a computer/cell repair shop resolder the port back on board. It takes a little bit of skill to do the delicate soldering involved in reconnecting or replacing a charge port when soldered to a board. Find below link to disassemble your device and a link just to show what is involved in the repair/replacement of USB mini port. Good luck.
