To watch a DVD or use advanced settings, the parking brake must be engaged. While bypasses existed (grounding the wire or installing a relay), they were trickier than on global models due to the gyroscope sensor also checking for vehicle motion.
The most infamous problem. The DRZ99 (and the DRZ90 before it) had a security password feature . If the car battery died, was disconnected, or if you removed the unit, it would demand a 4-digit password upon reboot. The default was often set by the installer (commonly "0000" or "1234"). But if the original owner didn't disable this feature, and you bought a used unit from Yahoo Auctions Japan (where many ended up), you now owned a $2,000 brick. There was no master override. Pioneer Japan would not help non-Japanese residents. Countless forum threads from Australia, Russia, and the US end with: "Bought a DRZ99. Battery died. Now it's a paperweight.
