Use this when you are physically removing the factory radio and clipping in the MK4 fascia and trim. For fitment and kit-contents checks before you start, use install before you begin; for power, earth, and speaker wiring after the stack is in, use the harness guide.
Quick answer
Clips that will not bite or a gap along one edge on MK4 usually means trim order is wrong or the loom is bunched behind the stack - re-offer the assembly square, relieve harness bulk, then clip evenly before final screws.
Problem
- You are swapping the factory radio stack for the MK4 fascia and screen.
Symptoms
- Clips will not seat; gap on one side.
- Harness bundle trapped behind the screen.
- Wrong vehicle dash family.
Cause
- Wrong dash family, clip order, or a thick harness bundle behind the stack stops the fascia seating squarely.
Fix Step-by-step
- Disconnect battery negative if your procedure requires it near airbag trim.
- Remove surrounding trim; unplug looms and antenna; label if needed.
- Remove factory unit; move any brackets the PVS sheet specifies.
- Offer MK4 assembly square; clip evenly - no twist.
- Screws firm, not over-tight.
- Check gaps before zip-tying harnesses.
- Next: Route and plug the PVS harness, then run first-time setup.
Notes
- Fitment: Will it fit / what’s in the box
- Wiring: Harness
- Cameras: Camera wiring
- No boot after install: Power troubleshooting
