I just uploaded my latest trial by error and a lot of luck the lower unit is back 'online' ... you may have gotten an email but I'll paste what I wrote here:

oh boy ... got in the van last friday and my son said ... "dad ... what is region code not found mean?" ... my wife and I looked at each other and just groaned ... first thing my wife says ... is it still under warranty ?? yes it is but first I wanted to run some diagnostics as i wasn't lookin forward to tearing the lower unit back out again!!

So heres what I did as best I remember:

okay ... to reset region not found


shut down vehicle

remove all dvd's and turn key to accessories

open top dvd player by clock and insert known working dvd

click on ves mode and touch view video

get the video running on the front screen ... i think power to the lower unit should be off as I recall

then eject running dvd from the top player

turn off power to the car

turn power back on and insert same dvd into the bottom player

say a prayer and hope that resets the region not found error as it is now playing again as normal


I know this seems like a spongebob spin 3 times and touch a button but it worked ... and so far 4 days later the dvd lower unit still works ???
