Copied the parents Mercedes one so they could keep the original at home, and it works fine in the car.
I guess it depends on what system really? My dad has the pioneer AVIC-X1, That has a duel layer disk and copys work fine
Yup it definatly can be done, I have copied My merc one and audi one. Same reason, I had one pinched and cost me a flippin fortune to replace. Next car will do the same. Pete PS Nero does a good job.
