I have a 2008 Dodge GC SXT. I am having a problem with the HDD portion of the MyGig unit. All my songs have disappeared. I can not copy new music to the HDD. The available space is 0. They said it was an "internal" issue and entire unit would need to be replaced. I am not sure I agree with what I was told. They said nothing about software upgrades or re-inputing codes and would like another opinion before tossing out another $500+. Does anyone out in Auto world have any suggestions?
