   Tesla's 2025 Model S/X introduced a front bumper camera, sparking interest among older HW4-equipped owners. Recent success by @Tutrifour proves retrofits are possible for 2023 Model X and compatible vehicles.

1. Compatible Vehicles & Hardware Basics

  • Only HW4 (AI4) equipped pre-refresh Model S/X support this retrofit
  • All HW4 FSD computers have unused camera ports (physical compatibility)
  • Requires software flag change (Config ID 131) to activate functionality
  • Confirmed by Tesla researcher Green through community testing

2. Required Parts & Cost Breakdown

According to Not a Tesla App,Model X owners need these parts:

Part Cost
Front camera $200
Grille with camera cutout $80
Bumper harness $130
Washer pump $15
Washer tubing $30
Total $455
  • Installation time: 3-5 hours
  • Critical note: Requires custom coax cable (not sold by Tesla)

 

Model S differences:

  • Needs full bumper replacement
  • Costs significantly more
  • Takes 5-7 hours to install

3. Software Activation Process

  1. Physical installation alone won't enable the camera
  2. Must access Tesla service mode
  3. Modify Config ID 131 to activate
  4. This tricks the system into recognizing new hardware

 

   Without this change, the camera feed won't appear on-screen despite proper wiring.

4. FAQ: Installation & Compatibility

Q: Can 2024 Model 3 Highland get this retrofit?

A: Only late-production units with unused camera ports. Requires physical verification.

 

Q: Will Tesla offer official retrofits?

A: No current plans. Estimated $800-$1,200 if available later.
