Common Failure Causes And Typical Life

Installation Recommendations
- Use Suitable Tools: Use plastic trim tools to avoid damaging dashboard surfaces and the head unit bezel.
- Protect Against Static: Handle the controller by its edges to minimize electrostatic discharge risk. Ground yourself if possible.
