My InControl remote has seased to function, worked well for the first two weeks of its life but no longer. An error message comes up saying it has "gone to sleep" and that it will wake up the next time the engine is started - but it doesn't. I've tried rocking it, talking to it and shouting at it very loudly but it will not wake up! Anyone have any ideas as to how to wake it up - or is my battery about to go flat??
