The stereo is def the same (AR-100) I think there are a few differences in how the dash works - but I think the plugs and everything are likely the same.
I have the 2023 HRV which has the same stereo as the Civic, so I am going to follow along and see how this goes. The stock stereo sucks, the screen is far too dim imo.
I have a new 2023 HRV Sport which has the exact same stereo. I'd love to figure out how to save some of the options in the settings - specifically the gamma adjust - trying to brighten up my screen. Any idea how to save changes?
