Will this work with my current door wiring, or do I need new harnesses?

This mirror uses factory connector pins—if your CR-V came with powered mirrors, the harness is already there. If you're upgrading from manual mirrors, you'll need to verify your door loom supports power delivery before installation.

Does the blind-spot detection camera need calibration after install?

BSD modules typically require a system scan and reset through the vehicle's infotainment or a diagnostic tool after mirror installation. Your Honda dealer or a qualified tech can handle this in minutes.

What's the return window if the mirror doesn't work with my setup?

Contact ModSupply customer service with your VIN and photos of the connector type on your door. Returns are handled on a case-by-case basis depending on condition and installation status.
