I am leaving in a few weeks with the military, and I need to get my head unit un-bricked! I have an AVIC F90BT and I bought the SD upgrade cards from Pioneer. As seems to be common, I got through the first card with no problems, but after I hit 3% some kind of error occurred. I have called Pioneer, and they want me to send the unit back to them (I really don't want to). I need a step by step, in simple terms on how to fix my unit. I would even settle for getting it working under the old 2.0. I am lost without my radio/navi. Please help!
