Hey everyone, I have an 03 g35 coupe the radio just died on me and the steering wheel controls no long work it. A/C is stuck on a setting and no adjusting it.

I've been doing some research I know that the 03-04 g35s are the same in terms of radio but the 05+ are not compatible. However, I was wondering if the sedans are also the same in the 03-04 since I've only just been searching for coupes. Thanks.

Sedans and coupes of equivalent years (except 2007) are compatible, so long as you get the Bose/Not Bose the same.

If you go 03 to 04 though, make sure you get the face trim as well, as some early 03 radios are slightly different from an 04 and won't work with the 03 face plate.
