Will this bolt straight onto my Kona or do I need adapters?

This is a factory part designed for direct bolt-on installation at OEM mounting points. No adapters or fabrication needed — it bolts where the original mirror sat.

Do the power and heat functions work immediately after install, or do I need to reprogram anything?

Power and heat will function on compatible Kona models without additional coding, assuming your vehicle's electrical harness and wiring are intact. If functions don't activate, have a dealer check mirror module compatibility and wiring continuity.

What condition is this mirror in, and can I return it if something doesn't work?

This is an OEM-specification unit. Test the power and heating functions immediately after installation so you can identify any issues while return options are still available. Refer to ModSupply's return policy for specifics on your purchase window.
