I am about to upgrade firmware on my K5, and I see from the instructions and previous discussions here that I need to format the card as FAT32? But my Windows PC will not let me do that (have not checked on the Mac), and it seems strange on a new product to force an old and less effective file system. Do you support exFAT now?
I wanted to have K5 main unit hidden and somewhat secure from a tipover and vandals, and also high up with a clear view, so I drilled a hole through the fairing and mounted it behind. But that means it is hard to get to the unit to take the card out -- I basically have to uninstall. I simply do not want to ever remove that card again once the system is installed. I hope you will enable firmware in the app soon.
On the subject of installation: It would be better if you make the cables from the main unit different length, and maybe longer. I collected them in a flexible cable sock, but had to use a very large diameter because all the connectors ended up as a big lump. Or even better, use a single thick 0,5m cable from the main unit with all the connectors.
