Thanks. I figured I'd have to scrap it. I'll just use it for parts down the road, methinks. I don't suppose I could use any of what you are talking about from a MKII system, could I? And are those issues fixable in similar ways to fixing the flash memory? I'm close to just picking up a MKIV, but I'd like to use that as a true last resort. With the MKII, I don't have any nav, but OBC and the radio work.
