Hi guys my sat nav was working fine when I installed my Chinese head unit but do not use it as my journies are local, went to use it last weekend and it comes up no satnav software found, I go to set up to reload it and it comes up Nandflash I have tried reset button also dissconected the unit from power sauce overnight but just the same.
The SD card has sat in the unit since instillation when I tried it and it worked fine so I am assuming it couldn't get corrupted? any thoughts or a fix would be greatly appreated
Cheap SD cards do get corrupted. To the point of not being able to reformat it. When I get unit with GPS software I always copy it to the new better quality SD card. It has way better chances of survival in the car.
