I am still about to open it up, but I have a 2003 G35 sedan with the all famous radio ac controls problem.

I am searching and searching for last two days on the forums, and all I want to know is this:

There is a circuit board that fails that controls both the HU and the Climate controls.
Now if I buy just the climate controls, where does that hook up to?

Let's just say I don't want a radio, I just want the DD Kit with the AC controls! Now that the stock HU and the stock board is removed, where does this new AC control plug in?

I hope you understand my question, because I am a little confused: if you have the stock HU the AC controls are in the same board as the HU, but if you buy a DD kit with the AC controls, then where does the AC controls plug in!?

Thanks!

 

There is a separate plug for each the climate control and radio boards.

 

I ordered and installed the replacment audio finisher board from Infiniti, only to have the problem persist. I pulled the stereo head unit and sent it into these guys:

Upon return, re-assembled everthing and it's been working fine since. I read a million posts and theories about the issue, but I can attest that it is your stereo, although i suppose it can't hurt to install the "new" finisher board to prevent recurrence. BTW, there is a ribbon cable connecting the finisher board to the Bose unit, if that's what you were asking.

 

also, sorry - can't help or comment on the DD option or bypassing your stock HU, as i found repairing it back to stock to be the easiest and most reliable fix personally.

 

the ribbon, try and trim it...

or if that dont work, JDM DD Finisher with Controls is what you WILL need.
