Have a DMH-1770NEX I bought a year and a half ago. About 3 weeks ago, screen went completely black and I thought the unit was dead. Then randomly the splash screen came on with vertical lines through it. Now the splash screen comes up that says NEX on it, but it never gets farther than that! Backup camera works. I have heard the AVIC line has a series of crappy sd cards, does this model have this as well?
Anyone have any ideas on how to fix?
