Yes, I have noticed. I think it may have something to do with the heat. My radio is on top, but it gets pretty darn hot after I run for awhile. I am taking it apart soon to put a heat shield under my radio. It has gotten so hot at times that my CD player doesn't work and flashes some overheat message. I take the CD out and it is very hot to the touch. My guess is Dodge moved the radio higher up to lessen the heat, but even so my Gen 2 GTS still has a hot radio.
