have new sena 10c, have spent over three days trying new sd cards etc, now got them to format, bluetooth fine (stereo if you buy new headset!) cannot update to firmware 3.0 keeps saying problem with sd card, strange as it says this for three cards of different makes and Gb size! downloaded all sena apps for iPhone x however, and this is simple, how do I get the camera on line to see what the camera is viewing or to be able to align the camera on the helmet?
so, how do i update firmware ? how do I view the camera images? thanks
