Has anyone had to replace the Hard Drive in the MyGig? I have access to AM/FM/Sat but when I switch to the other inputs, it freezes for 7 minutes, then resets. I took it in to the dealership once and they told me it would be $2100 to replace the entire unit, but I think I could replace the HD for $130 and be okay. Still have access to NAV and UConnect. Any suggestions?
