For anyone that ever run into an issue were your radio don’t turn on and the A/C stay on 75 Auto but has no control functionality, check the fuse # 15 that’s in the area by the battery. I did a lot of research but did not find a straight answer other than taking the car to the stealership or sending my radio unit off for as long as a MONTH and paying $150-$200 (Sending it off), $350 (used), & $550 - $600 (dealer). When I get a chance I’ll try to scan or make a diagram of the fuse box by the battery sense I couldn’t find anything on Radio fuse for 2005 Infiniti G35x on Google.

Now I get to have a Happy Memorial Day to ME DOMO



HERE IS THE FIX - check fuse # 15 that’s in the area by the battery, UNDER THE HOOD...

This worked for me and only cost me the price of a box of fuses or did I use a spare fuse... either way it fixed it....

A lot of 2003 owners expeirence this

Has something to do with the radio circuit board taking out the HVAC controls as well

There have been threads on this. I'll see if i can find one

Oh snap i have this problem!

Thanks but I already figured it out. I guess I should've put FIXED before my subject in my title. But I figured out where the radio fuse was. easy fix... and tv&nav2go installed :-) Happy weekend for me...

yup...... its the circuit board.. few option to fix this problem without going to stealership is going aftermarket HU. I had the same problem and after going with pioneer HU, all that problem is gone. the other choice is fixing it by the stealership or buy another stock HU.

I found this thread, seems like there is a recall on it of some sort:

"On some model year 2003 G35 Sedans manufactured through August 21, 2002, the audio and temperature controls may not operate as expected. When using the audio equipment or the temperature controls, the unit may become inoperative. In some cases, this can be corrected by turning the ignition switch off and back on again. In other cases, the unit remains inoperative and requires service by an Infiniti technician. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to replace the audio finisher circuit board on these vehicles. Use Infiniti Net to confirm if a specific vehicle is affected by this service campaign (P3104).

this will be the last thread, as i have stopped looking.....

yup.... you gotta b!tch slap your bose HU! it worked on mine until i got tired of it and the stock HU stop working.....it will come to the point where you keep hitting your HU and will turn off right away. You have to hit the damn thing pretty hard. I broke one of the button by hitting it too much. Just go DD! good luck!

Most problems are occuring with 2003 models.


However, this did happen ONE time with my 2006. Same symtoms and everything. I just shut my car off, restarted it and problem was gone. Hasn't happened since. Hope it's a fluke

ive had the same problem infiniti in canada has a program going on for this situation right now u bring ur old radio in and swap it for a rebuilt one took 3 days to get it but the rebuilt ones have all the kinks figured out it cost me 450 and it now works great

P.S. i was told if u live in a cold climat that u shouldn;t use the cd player untill its warmed up inside the car it helps on wear and tear on the inturnal parts inside the cd player cuz everything is sliff in there wen its cold it made sence to me so i baby my new cd player lol

so the same thing happened to me and before you jump to conclusionssss that you need a new radio


check your mirror fuse... mine did this the other day so we checked all the fuses and my mirror fuse(10a) blew out.. and i was like hmmm that shouldn't cause it but who knows so i replaced the fuse... guess what?!?1 i have a radio and control of my a/c again
