Quick answer
Before removing the factory radio, confirm the 200 mm 2008+ 70 Series opening and unbox harness, fascia, mic, and hardware - the narrow early steel-dash radio slot is not MK4-compatible, so photograph the opening if you are unsure.
Problem
- You need to confirm MK4 fitment and kit contents before removing the factory radio.
Symptoms
- Unsure if the dash is the supported 200 mm opening.
- Steel-dash vs later plastic dash confusion.
- Missing harness, fascia, or mic before you start.
Cause
- A prior aftermarket install left non-standard adapters or unknown tap points.
Fix Step-by-step
- Unbox: headunit, fascia, Toyota power/speaker harness, hardware, external mic, quick-start / QR.
- Confirm 200 mm factory radio opening on supported 2008+ 70 Series.
- Not compatible with early narrow steel-dash slot.
- Photo the opening if unsure; do not force trim.
- Use trim tools; bag screws; protect the console.
Notes
- Next: Remove factory radio and fit fascia
