Umm actually on certain models the guy from best buy may be correct.

we have a databus in our car and it remotly connects the radio to the door chimes, and other chimes (not sure about the airbag) but i doubt its that extreme.

The worst that might happen is if you replace your radio you would lose your low gas chime and door chimes but im thinkin thats about it for that. You can relocate the factory radio and keep everything if you want.

Btw this is only on 2001+ models
