Yesterday while flying my M2P (warm day), started getting processor overload error message on my Ipad Mini gen 4 screen. First time ever since flying the M2P. I've read the cautions on this forum about flying with the Ipad Mini gen 4 and finally had it happen. So, my question is.....when I upgrade to the Ipad Mini gen 5, is there any advantage to getting a cellular model without activating the service? This model supports GPS whereas the standard models using wifi do not.
