Thread: Which up-datable unit ?

The downloaded map should automatically unzip to a new map FOLDER and THAT'S what should go on the card, not all the individual files.

Try running F/A from the card BUT via a card reader, not the device.
If it works you should/will get a new file inside the map folder called ***.meta.dct

PS You'll need to copy the ttgo.bif file from internal memory to the SD card for F/A to work on that new map if it's through a card reader.
PPS you only need the ttgo.bif & new map folder on the SD card on these devices, nothing more like voices etc as they can stay internally
