NAV3 removes the map from the card.

Format ur SD-Card in Windows 10/7 to FAT32 and put it back in your Device. If u have put ur SD-Card in your Device, it will ask u to format ur SD-Card, click yes and then put ur Maps again to your SD-Card with R-link explorer.

goldpritt Reviewed by goldpritt on 26th December 2022. NAV3 removes the map from the card. Hello. Format the card in the device, then to the card reader and copy the R-link explorer maps. I put the card into the device (turned on or off without meaning) and "reading the card" as wanted "blank card". I have to do this several times or change the card and it will work out some time. 8GB or 16GB cards. Do I only have this problem often? Rating: 5
