Backup form Navi


first thing first: sorry for my bad english - i’ am a german boy!

Anyway, I have a problem making a running Backup from the Toyota Corolla Navigation DVD.

The problem seems to be that the dvd is a DL DVD-ROM with PTP format. Furthermore all discs they i found at local stores (so far) are OTP.

Is there a method (program?) to burn DVDR DL in PTP and set a manual layerbreak?
Or can you suggest DVDR DLs with PTP?

Thanks in advance

By the way: Is there anyone who successfully made a running backup of a Toyota Navigation DVD (Touchscreen)?

No way.

Using search would have already shown you this.
