OK, discovered what double din stands for now the big question

Will a bose head unit from a '04 coupe car without Nav fit into an 03 sedan with nav?

Anyone know?

Thanks,

Joe

the audio and hvac controls share the same board, thats where the problem is.

screw the stealership, they'll end up ripping you off almost every single time.

you have 2 choices 1) get an aftermarket unit (thats what i'm doing) 2) there's a shop in san jose ca that refurbishes these. here's their website www.shortcircuitrepair.com

The problem isn't the board, it has been replaced twice.

Is this specific to 2003, can I switch in a 2004 and be ok?

I believe that you can, but do some more research to make sure. I know that the 2005 model can't be switched in.

I have the same issue. Difference is, after a few times, the steering controls stopped working too.

An unusual question:
I have a iPhone, iPod dock. I don't plan to use CDs anymore. So...

Q) Is it possible to just disconnect the CD player and solve this problem? Will I have my A/C controls back working? If yes, Is there a simple way to plug in my iPod dock through some RCA interface or something directly to the speakers? just to us the car's sound system.

There are several different ipod adapters that you can buy and hook up. Just do a search for Ipod adapter g35. As to disconnecting the CD player, dunno.

I have an OEM '06 stereo for sale ... cd changer and finisher w/ stereo contols..

Finally, a definitive answer. Yup, mine's doing this, too. So pay stealership 500-600 for an installed, refurbished Bose HU or go aftermarket? I'd like to go aftermarket, but I don't need nav, ipod or anything else, FM/CD will do just fine. Hmm, maybe MP3. Any recommendations for good-quality, simple units for $500ish all-in?

So how does that control my HVAC, then? I need the JDM piece for that, yes? Clearly I'm still not getting it... :dunno:

Greetings,

The board you are referring to is called the "finisher" board. It is not the usual suspect with these problems. The most common problem with these radios is the power supply fails. We can repair these units and offer a 1 year warranty on the repair.
We repair approximately 4-5 G35 radios a week mostly for dealerships.

Our turn around time is usually 1-2 days and it will be shipped out promptly.

I kno exactly how to fix your problem!!! I me and my brother in law found the solution by accident!!! Il take a pic if need be. So we were taking the radio out to install my pxamg ipod kit in by g35 coupe 2005. When we put the radio back in I had the same problem as you. Naturally I freaked out. But my brother in law who is a genius found out that this little thing thats VERY VERY VERRRRY senstive when moved easily falls out of place turns off the WHOLE radio and ac controls and the ac goes crazy sometimes. So you can try punching the RIGHT BOTTOM side of your radio or if you really want take the whole radio out and look at the bottom right side of it and youll see this little thing that if you wiggle it a little it should go back the way its supposed too. It then fixes everything and BAM! u save 1000 dollars cuz the dealerships stupid and "didnt know" about this tiny little thing that when moved a tiny bit makes your radio and ac go haywire. Hope this helps everyone. If possible please make this a sticky so no one else makes the mistake of paying a lot of money to fix a relatively small issue to fix.
