GPS Repair Problems? Ask a GPS Technician for Answers ASAP
Hi there and welcome
When the update fails, can you tell me if it gives an error message or it just disconnects?
It points to either a faulty card or internal memory on the unit.
Can you get a different SD card, copy the contents to it from the other SD card and tell me if that then updates please.
Ok, if it is empty then there is no content to copy over, so try a different card please.
