I received my update disc for the clock issue on my 2002 MDX. I followed the directions and the screen said updating.... once it was finished I poped out the update disk and inserted the 2007 Nav DVD I still use. Now the screen says there is a problem with the disc (the Nav disc) and to contact your dealer. I've removed and re inserted the Nav disc several times over the last week, same response. I've tried it with the key on Acc and X running. Same error message. Anyone else have this issue? Thanks Oh, and my clock is still not working.
