If you have a dvd read-write, it should work.....
You do need to copy it to either the DVD-R minus (-) or DVD-R plus(+). I was able to copy it to both the plus and the minus DVD, but only one of them would actually work when I plugged it back into my navigation in the trunk. For the life of me, I can't remember which one works....plus or minus.
Your computer disk drive should be able to read it. I use Nero software to make the copies.
It can be done.
