Dear Friends,

I burned 2 version of navi iso file to Verbatim and Sony DVD R+DL, but my VERSO(2005) GEN3 navi is not like it.
It is shows "unable to read DVD".
I set the burning parameters according the descripted method, I wrote 1x speed and booktype also set to DVD-ROM,
I unplugged battery (-) terminal also for 10minutes, but it is not helped...
I think the problem is not the iso file and the burning method, because two different iso file, and two different DVD brand generate same
error message.
I need your help my friends, please recommend for me a solution.
(The original West europe dvd is working well, I would like to use East Europe navigation)
Thank you in advance
Roland
