Xoutpost.com - MKIV - doesn't take a new disk

Gents,
have a built in navi. I think it has the latest v.32 OS on MKIV.
After some years, the DVD finally gave up and died. I burned the 2012 east cost iso i have, but it won't take it with "Incorrect DVD in navigational unit" type of message.

so i looked inside the 2009 iso and 2012 - they have drastically different folder structures.

2009:

Code:

-r-xr-xr-x 1 root root    758 Aug  8  2007 abstract

-r-xr-xr-x 1 root root     38 Aug  8  2007 bibliogr

-r-xr-xr-x 1 root root 750592 Aug  8  2007 carinet

-r-xr-xr-x 1 root root    601 Aug  8  2007 copyrigh

dr-xr-xr-x 1 root root   2048 Aug  8  2007 db

dr-xr-xr-x 1 root root   2048 Aug  8  2007 tpd

2012:

Code:

-r--r--r-- 1 4294967295 4294967295  545 Jun 28  2011 cdrom.toc

Question:
do i have a wrong iso for 2012 or i'm just been a silly rabbit?
and if i have a wrong 2012, how should it look like "inside" ?

Thank you
