AndeyHall Posted May 1, 2011 Report Share Posted May 1, 2011 A friend of mine has a D3 in his diesel F250 and if you turn the key switch backward to auxiliary, the unit turns on just fine, but when you turn the key to run once the truck has been cranked, the unit takes about a minute before it ever starts booting up. Anybody had this issue? Quote Link to post Share on other sites
