Hello,
just got X3 with Navi. I read xoutpost navi faq, but still confused which version do i have. Here are a few pics that i made. Please advise. Thank you.

I also tried to upgrade it ( you can see that it reports MKIV ), but with no luck. Please see images attached. Unit reads neither maps dvd nor 22, 28 , 32 software cd i burned ( i burned with 4, 6, 8 and 16 speeds on 2 types of media).
Same sequence of messages:
"cd check". i can hear it's spinning the disk, then "CD Error" and "no cd in the nav unit".
This sequence applies to both OS cd s and Maps.
Please advise.
