Here are the instruction for reformatting with a MAC
Simon
Okay, then lets try and format the card and reload the charting to see if that will allow the charts to display on your unit.
To format and reset your Navionics card, follow the steps below:
1.
Insert your Navionics card into the card reader on your Mac.
2.
Left click on the “Spotlight” icon.
3.
Type in “Disk Utility” and then press the “Enter” key.
4.
On the left panel, left click on the SD card.
5.
Left click on the “Erase” tab at the top. (Located next to “First Aid”, “RAID” and “Restore”)
6.
Choose “FAT” or "MS DOS (FAT)" from the “Format” drop menu.
7.
Left click on the “Erase” button.
8.
You will receive a message asking if you want to erase the card. Click “Erase”.
9.
Empty your Trash bin on your computer.
10.
Copy the "ntag.txt" file attached to this email directly onto the cartridge once the format is complete.
11.
Launch the Chart Installer and perform the Freshest Data Update to download the chart files back to your card.
+xHi all,
Thanks so much for the replies. We had tried the card adapter but not had any luck so will contact Navionics directly as you have suggested Simon. Thank you so much! Will keep our fingers crossed we share your success!
Kind regards,
Jane
