I've got an 80G Video with 1.2.1... and my setup seems to be devolving day by day. Today the stereo wouldn't even recognize that the DICE is installed (MODE button toggles from radio to tape only). Rebooted the iPod again but nothing changed.

I am running an old NAV firmware (I have a 2001). Would an upgrade to v22 do anything?

Thanks for any help.
