My mom has a 99 GMC savana conversion van and she has had two Kenwood head units and both goes into protect with the heat more than 3/4 the way up after about 10 mins. So I tried The head unit she has now in my car with the heat fully up and everything was fine. What could be the problem in her van? Even if the heat is on defrost the radio still goes into protect and during the hot summer days the radio never went into protect.
