The AVIC-DRV250 reads DVD-ROM or DVD-R media. Avoid using DVD+R or DVD-RW (re-writable) discs, as the older lasers in these units often lack the reflectivity to read them.
Legacy car optical drives are highly sensitive to media types and the speed at which data is written. Standard CD-Rs generally lack the capacity required for these map and system files, meaning you will need a blank DVD-R.
