I’ve just installed a Mega Live Imaging transducer on my Ultrex and connected it directly into the back of my Helix 12 DI+ GPS G3 unit.
The instructions said to update the software to 2.280 first before updating to version 2.750. So I updated to 2.280 as it said Then I erased/formatted the same SD card and loaded it with version 2.750 but the Helix doesn’t even recognize the SD card is in the unit.
Anyone else have this issue? How can the unit recognize the card to upgrade to 2.280 but not 2.750.
Help, please!!!!!
