CD/DVD and format limitations: In view of the variety of CDs/DVDs and the difference in memory capacities, the functionality may be restricted in the case of some storage devices. Under certain circumstances, audio CDs/video DVDs that are copy-protected or CDs/DVDs that do not comply with the standard audio format, and multisession CDs cannot be played at all, or the functionality may be limited. We recommend always finalising the burning process when creating multisession CDs. Multisession is not supported for DVDs.
Handling CDs/DVDs, the CD drive or the DVD drive: To ensure perfect, high-quality playback and avoid scanning errors or damage to the media drive, always store CDs/DVDs in a suitable case and do not expose them to direct sunlight. Do not use:
- Damaged, dirty or scratched CDs/DVDs
- Single CDs/DVDs (diameter 8 cm / 3 inches)
- Non-circular CDs/DVDs (shape CDs)
- CDs/DVDs with stickers
- Protective rings
- Cleaning discs
Thermal cut-out: In the case of unusually hot or cold outside temperatures, it is possible that CD/DVD playback will temporarily not be possible. A thermal cut-out is installed to protect the CD/DVD and the reading laser.
Laser devices: Laser devices are divided into the safety classes 1 to 4, as specified by DIN IEC 76 (CO) 6/VDE 0837. The optical readers installed in your Audi Q7 are classified as safety class 1. Lasers used in devices that fall into this category are very weak and well screened, so there is no danger if used correctly.
