Trying to export data from my back unit, 688CI HD, to my front unit a Helix 5. I had to purchase a new SD card with the micro card in it and got a 64 GB SanDisk. I keep getting a fail when I try to export, but if I use my old 2 GB card it is successful. Is this new card "too much" for the unit? If so I stopped back at a store and the micro cards seem all to have a high GB count. Could I get someone with computer knowledge to transfer the date from the 2.0 card to the new one? Thanks
