Landcruiser Sat Nav

[yrob]

I wonder if anyone could help.

I have a 2003 (53) LC5 and It's fantastic - had from new.. I however over the past couple of years had a problem with my sat nav unit and I'm at the point where I just want to get it resolved. My issue is that I get the message

unable to read dvd correctly. Check if the dvd is damaged or dirty

I basically cant use the unit for direction and thats causing pain.

I did a few years ago have a copy of a new DVD posted to me and after some deliberation I wondered if that may be my issue. Due to a nasty marital split I cant get access to the original DVD. I've been into my local dealer too and they struggle to get the disk to eject from the unit and basically couldnt help.

I wonder if there was anyone out there that had a similar experience that could help. I would be so very grateful.

Regards,

Rob
