I will be taking my R/T in for a T56 alternator exchange for the recall on Fri. They have viewed the serial # of my unit as needing to be replaced. No one at the dealership could answer my ques. of the hard drive content I have put into my radio which was quite time consuming into many many untold hrs. of c/d music. The radio is a 2014. Does anyone know if I should expect to lose all my hard drive content when they disconnect the battery for a couple hrs. while they exchange my alternator? They claim theres no equipment at any dealership that will let them remove the hard drive content, store it briefly then reinsert it back into my hard drive when the battery is reconnected. Thks in advance.
