@kingsleytrucking: ✅ 1. Digital Tachograph Card Slot It reads driver smart cards to log: Driving hours Rest times Vehicle speed Distance travelled Common in fleet trucks, especially Euro 4-compliant vehicles or imports from markets with strict transport laws (e.g., Europe or the Middle East). ✅ 2. May Also Be a Dummy Slot (If Not Active) If your truck doesn’t use a tachograph, this could be a dummy cover for where the device would be installed in some models. Isuzu often uses standard dashboards across different specs, so some slots might be unused in your market (Kenya).
