Any 64GB cards that work in these cameras are more good luck than good management, realistically if the camera can't format the card then there's a higher risk that it will let you down when you need it most
im sorry....but each singel dash cam that is in this forum has to be tested for reliability first before you can trust it, each single peace you receive....whther it is fake, whether it is already defective, whether it is reliable....the same goes for the flash cards, them not working in any device is known since thy exist...
and after that testing by the user is passed, i cant see how a card that always worked fine will suddenly stop working in the crucial moment
it is really nood good luck, the "hardware" controllers just can handle these bigger cards, they dont produce nowadays extra old ones and new ones for sdxc....it is the same piece....
that phenomenom is not only in the dash cam world, also tablets and handys and whatever devices that are not supposed to handle the 64gb cards, do it anyway, the internet is full with guides for this.... and probably millions users use them already on devices that arent supposed to be able to handle them regarding manufacturer of these devices
just because you cant run a firmware routine to format the card that is not supported, doesnt mean anything
most of these dash cams are simply fiddled together....with parts that would amaze most of us both positivly and negativly
the quality testing is also...
well...you can probably understand what im trying to say....there are many factors, to think it will be unreliable through that card is ....well... unreasonable.... maybe it will be a "little more" unreliable as it is normaly
