This is the top-tier navigation package of its era. It features a larger high-resolution screen compared to the basic Audio 20 system. Check for map loading times and active navigation capabilities to verify system health.
🚨 Avoid Retrofit Frauds:Always decode the VIN configuration rather than relying on visual trims. Sellers frequently install visual replicas (such as speaker covers or AMG body panels) on standard vehicles to charge a premium. A genuine datacard decode matches the vehicle's manufacturing specifications on the day it rolled off the assembly line.
