And if they are actually changing manufacturers it could be quite a while before the supplies catch up. I read the radio was made by harmon kardon.
If the 8.4an fails is the whole truck undrivable? I picked up my 2013 Laramie Quad Cab,8spd with the hemi 2 days ago and everything has worked perfect. just hope it stays that way.There must be thousands of these radio in service. Are they all going to fail or just a small percentage. Electronics tend to be fickle, any part that is weak for whatever reason can cause it to quit.
