I have an Alpine sat nav system on which I have/had a 2001 version 1 sat nav disk.
I made a copy of this disc using Verbatim DL DVD-R disc, using DVD Decrypter, when I tested this disc it worked fine in my sat nav unit.
SO I managed to get hold of a new 2006 version 3 disk which I made an ISO image of on my hard drive, I followed all the same procedures as my previous old disc and when I inserted the disc in the navi unit, it instanstly downloaded the updated software but then came up with a message telling me that it was unable to read the data.
So I then tried using DL DVD+R discs, but I still get the same message 'Unable to read data' no matter what speed or what software I use, I cannot get the disc to run on the navi unit.
I thought it was due to the Path track type as when I checked the two discs (original and copy) that was the only difference between the two. But now as people above are saying its not possible I do not know why the copies are not working.
Any suggestions?
