✅ Fitment & Compatibility (Exact / No Guessing)
This item is a classic in‑dash head unit. Because it’s not supplied with a verified make/model/year list on eBay, we do not publish vehicle-year fitment claims. Instead, use the checklist below and message us if you want confirmation before purchase.
| Fitment check (must match) | Why it matters | Status |
|---|---|---|
| Model / label matches (CN‑SH133A / YEFM01430) | Prevents ordering the wrong version | Required |
| Vehicle electrical system: 12V (negative ground) | 24V vehicles (many trucks/plant) are not suitable without conversion | Required |
| Speaker impedance: 4Ω system | Mismatch can cause poor sound or overheating | Required |
| Dash opening & mounts match your current in‑dash radio style | Different dashboards use different brackets/cages | Verify by photo |
| Wiring/connector compatibility | May require an adapter harness (varies by vehicle) | Often required |
🚫 Clear “Will / Won’t Fit” Guidance
Most likely to suit when verified
- Cars with an in‑dash radio opening and conventional mounting brackets/cage
- Vehicles with 12V negative-ground electrical systems
- Cars with 4Ω speakers and standard analogue speaker wiring
Not suitable / avoid do not buy
- 24V vehicles (unless professionally converted)
- Vehicles with fully integrated infotainment (screen/HVAC combined) where the radio cannot be separated
- Cars that require data-bus / fibre optic audio interfaces unless you already have the correct converter hardware
