Hi everyone,
Recently got a new to me 2009 Fit and I love the car but do miss steering wheel audio controls. I found the thread on how to add the controls to a Fit with the OEM radio but this one came with an aftermarket double din. I couldn't find a straightforward thread detailing how to do this swap. I have set of controls and experience adding audio controls to 8th gen civics so I'm not afraid to get in there but my experience has always been with adding it to OEM radios.

Any help or guidance would be helpful. Thank you!
