The Mercedes S Class average ($316) runs 17% above its median ($271), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 10 model years for the Mercedes S Class (2015–2024) but only 7 for the Cadillac XT4 (2019–2025), so the Mercedes S Class data reflects a broader range of generations.
The Mercedes S Class car radio is interchangeable across 15 model years versus just 9 for the Cadillac XT4 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Cadillac XT4 is 46% cheaper ($147 vs $270) — the gap widens compared to the overall median difference.
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.
