GPS Navigation DVD Back-up

[Goldy86911]

I'm wondering if I can back-up my copy of a GPS Navigation DVD?
I just made a disc image of the DVD using Alcohol 120%.
It appears that the size of the data is almost 6 gig.
Do you think I could burn that image to a dual layer dvd so that it will work in my Nav system in my new car?
If anyone has done this I would appreciate the feedback.
Thanks!!!

I suspect not. I have a feeling those DVDs are written PTP and not OPT.

I don't think ImgBurn writes PTP. You might like to also ask at ImgBurn Forum.

Thanks Blu
So even though I made the image and try to copy that same image on a DVD
you don't think it will work? Isn't the copy the same as the original?
