I purchased this for a Cyber Navi map data update, but I'm selling it because I couldn't replace the hard drive myself. It's unopened, brand new, and unused. The HDD is new. The map data is 2021, version 2.1.2. The speed camera data is from 2022. According to the product description when I bought it, the compatible models are Carrozzeria AVIC-ZH99, ZH09, ZH07, ZH77, VH99, VH09, and VH09CS. It was stated that it's for navigation repair, as it will be locked and unusable if used outside of a navigation system.
