Buyer's checklist
What to check before buying a used car radio
- Verify anti-theft security unlock code availability or whether the unit is anti-theft VIN-locked to the donor vehicle requiring dealer authorization.
- Match option codes for factory amplified audio systems (e.g., Bose, JBL, Harman Kardon), touchscreens, navigation modules, and steering wheel control interfaces.
- Inspect the rear connector block for bent pins, cut harness pigtails, or damaged antenna and satellite tuner connections.
- Ask for confirmation that the touchscreen digitizer, Bluetooth connectivity, and internal disc drive function without freeze-ups or dead zones.
