Almost killed my battery couple days ago...-43 and not being plugged in will do that. plugged the charger onto it and got it fired up. The Gryphon screen would not display until truck warmed up. Thought to myself....weak battery=tunes lost.:weeping: when truck warmed up, went into menu and seen they were still there
This little box is tough.
