my sti driver has begun to give a false K band alert when i switch it on in the morning and its left in my car. it usually freezing or below (-10 or -15) so its not a heat problem. when i shut it off and replug it in its fine. im wondering if this is a known problem and how should i fix it ? in warmer weather it never used to give this problem. the k band stays on all the time until i shut it off manually. a4m9 firmware.
