congratulations on your car getting back the way it's supposed to be...no thanks to Infiniti! :shades: BigMurth

He repairs the actual defective unit.
C told me that my G35 had already had the service recall done. When I suggested that the service had been to replace one defective part with another, C said that defects were covered by the manufacturer's warranty, no longer in effect. She was polite but unyielding, like many of my former girlfriends.
Does anyone know of a good audio repair shop in Charlotte?
I have read all the previous posts.
I have a friend who is an electronics fixer guru who can help.
What we need to know is the information related to the bug on the board.
We need to know what goes wrong and what needs to be fixed.
Is it a component, bad solder joint, etc????
If these radio shops can fix them so can we.
Who has the knowledge? Who can help us out here.
I am in Canada and really don't want to send to Florida if we can fix here on site.
Thnxs, hope someone out there can pin point the bug.
I had multiple problems and changed out the stereo with a 2 dinn (that's the size of it) Clarion that I'm not real happy with and a a metra kit that changed out the heat/ac control. That fixed the dash light and heat/ac issue.
I then still had a battery drain. I had the tech disconnect the rear woofer...didn't help the drain. I then took it to the dealer and they changed out the stinking starter.
I haven't had a single baterry problem since.
Don't know exactly where the problem was. Just wanted everything out that could have caused it.
If you are having just a battery drain issue it may not be the stereo. Check out earlier posts by Big Murth since he seems to be the man.
Good Luck
Because I have a 1/2 amp drain problem and pulling the radio fuse restores the draw to normal amperage it is highly suspect the problem is in the radio circuit bd.
I do my own service and repairs so it is doubtful Infiniti will want to find dollars to help me out and I understand that.
My bet is that there is a $2.00 component on the radio bd that is the bug and all that is required is that it needs to be replaced. I want to find out what that component is and fix it myself.
If Infiniti offered your positive experience to everyone then there wouldn't be pages of posts here of upset owners complaining about the issues.
I also stopped at the local car stereo installer to pic his brain. They didn't know much about the issues but admitted to installing the Metra 99-7604 kit on a G35 but they did not seem that excited about getting involved with it and helping me out.
The most promising solution seems to be is to send the board off to Florida for repair although I would still like to have a wack at repairing the board myself if I could just get a bit more info on what the issue is with the board.
Interesting.... they know all about the problems and offered two solutions. I asked for assistance with a fix for the problem and they offered to sell me a $12. service manual for the radio/cassette/cd player.
They also said I could bring the unit to them and they would install an upgrade kit that would improve reliability and performance and would probably fix the drain problem. Cost for this service was about $225. I took the service manual and at this time PD is being done and I will update soon.
If anyone has any ideas how to fix this, or knows some cheap technician who can do it in the DC area, email me back please.
Thanks

actually the "most promising solution " is to replace the radio with the metra kit or jdm I have a 03 g35 sedan and started having the same issues last year..my dash would die my cd changer failed and started having issues with the a/c controls..Last month i went ahead and got the metra kit bought a new radio and installed it myself..total cost was $ 400 (coz i bought and expensive kenwood head unit) the metra kit was $100 and now my car sounds great..i no longer have a/c control issues and can now drive without worrying whether my cd player will work or if my heater will function on a cold morning..
alot of pple have had the board fixed but the issue resurfaces each time..so your best bet to save time and energy and at the same time upgrade your car is to get rid of the radio
As I said before Oakvil** Infiniti was not much help. All they could do was offer to install a brand new radio for me. I explained to them there was a place in Florida that could repair the radio logic bd for me at a cost of a few hundred dollars, a fraction of the cost of replacing the radio. I asked them if there was a place locally that could do this? They said there was nothing.
I made some more inquiries. Clarion's main office and service center was an 8 minute drive from the Qakvil** Infiniti dealer. I thought I would drop by Clarion and pick their brains about the issue.
Bingo!... They said they were well aware of the problems and would be happy to sell me a service manual for the radio assembly or for $225. they would install an upgrade kit to the assembly that addresses the issues. Nice! Friendly folks with multiple options and solutions at a reasonable price.
Now we are getting somewhere!
For now I have the manual in hand and will update the progress as we proceed.
Once again Infiniti was no help and without a doubt knew all about the Clarion offerings.
I took the radio assembly out last week.
I forgot to take the CD's out of the deck so took the unit back to the car and plugged the three connectors back into the back of the unit to see if I could get the CD's out.
... As soon as I inserted the last connector the radio/CD unit comes alive and out pops a CD????
There is no key in the ignition and the car is off! Interesting to say the least and the first clue to locating the bug.
I could not figure out how to separate the top and bottom units which would allow access to the board in question.
I then handed the unit over to my pal would wanted to have a stab at it.
He called a couple days later. He figured out how to get at the board and was doing a full PD on the board. He discovered something interesting. He had me take some voltage measurements at the car here (he is in another city an hour away).
Well what do you know..... Looks like he may have found the bug, the cause of the parasite drain.
The bug appears to be a manufacturing error on the board. My pal made a change to the board. I got the unit back from my pal and installed it last week.
I did some amp checks and confirmed the battery drain problem is gone!!!!!!!!!!!!
The reading between the -post and ground was about .55 (with the battery drain issue), and is now sitting at .07 With the radio fuse out it was/is .05 so a huge improvement.
The only issue I have now is I have lost one feature. If the radio is on when I turn the car off, it is off when I turn the car back on. I then have to physically hit the radio on button to turn the radio back on. May be a memory support voltage or line issue.
Will do some further checks to see if this issue can be corrected. I may have put this bug on the vehicle when taking it apart and reassembling.
Will let you know what I find out. Need to wait for a warmer day as the car is outside and this is Canada...lol
So far the cost to fix has been $12. for the manual.
Wow I didn't know Best buy can install the metra kit/harness for us. I am really interested in doing the same with my Infiniti and then selling it. I have a G35 2003 sedan. If you can please email a link to the Metra dash kit and Metra amp harness then I can order it online. I will go to Best buy and get the CD/radio that can fit an Infiniti. It seems this is the best solution. I have been send around in circles by the dealer about fixing this, and they told me $2000 bucks to replace a simple dumb circuit board! Currently my CD/Radio and Heating/AC is stuck at the last channel setting.
Thanks for your help buddy!

I love my G35, but I still think I should sell it now :-) done with Nissans and Infinitis

I am in the same spot as post #225 bookmarks in Canada . I have a 2003 G35 , all the same issues with the radio not working, air conditioning on full blast and it seems every time we start the car there different things coming on or not working at all . Oakville Nissan/Infiniti quoted over $1500 to repair . As well the driver side window goes up and down never stopping at the top for the third time, the pillars between the doors are rusted through and the headlights are full of condensation . They claim that if I change the radio I will still need a board for $800 or it won't work. I am currently going to Nissan Canada as well . How did you make out with Nissan Canada ? My first contact wasn't at all hopeful. The 370Z we were contemplating isn't going to happen after this
Thanks

So like many on here, I have had the unfortunate situation the last few weeks of no radio controls and AC blowing. Fortunately, it is not on max blast right now, so that is okay... I have a Navi on my 2003 G35 sedan and doing some research on the web, i read that it is more complicated to go the aftermarket route.. I really rather not go to the Infiniti stealership. Has anyone with a Nav solved this with some of the aftermarket solutions?
I purchased Metra kit ($159.00) since it has its own AC control. By doing this, there is no radio that can mess up my AC. ( I found out that there was a recall on this issue. However, it only applies to G35 that was manufactured before Aug.21, 2002 which tells me that factory radio will fail again. ) I had big concern about my Nav because I didn't want it to be just a decoration. 2 screws that I remove from original panel had no place for metra thus making the Nav unit unstable. Also nav button was a tight squeeze that it requires shaving. Since I didn't have the right tools, I installed the unit back into the car as is. Navigation, MPG, and everything works except audio. Once I press the nav unit down, it needs some banging on the side panel for it to pop out slowly. Working in slow pace, the process took 3 hours. It shoud take less than an hour second time around. I received confidence by watching radio removal video from infinitihelp.com
Since then I have puchased metra harness (70-7551) and antenna adaptor (40-NI20). I am debating on what head unit to purchase... but when I do.. I will probably fix the Nav unit as well. I will let you know once I fix everything.
The battery drain problem is fixed but I have not had time to look into the memory store issue. using the car daily and the memory problem is very minor and I can live with it.
If I had to do it all over again I would take the radio.deck out myself and take the unit to Clarion's repair shop in Mississaga. For a few hundred dollars they will work their magic. I would not got to Infiniti for a new radio. What a rip off.
About a year ago, I found a thread on some site and wish I had saved it. An electrical engineer had explained that there is an overload diode in the radio that can't handle the amps from all the systems (radio, A/C, Nav, etc.) and consequently, it breaks. The result of this failed diode is that the radio will continue to draw too much current (can't remember the exact amperage) when the car is not running instead of a minuscule amount, as normal. If the car sits for more than like 24 hours, the battery will be dead. If you do drive the vehicle daily, you never do notice this battery drain. I went through 2 different batteries and other trouble shooting before I found his thread. The first time, 2 days after I bought a battery, it was dead and I was pulling my hair out. To get to the issue...
He suggested pulling the radio fuse out of the fuse box when you know you won't be driving the vehicle for more than a day. I started doing that and I never had any drained battery issues EVER again. The only downside to this is that you lose all station memory locations and while the fuse is out, you have no A/C controls... but at least your car will always start. I know it's a hassle, but I wasn't going to spend $1800 for a dealership to replace the radio nor around $800 for them to fix the diode with labor and parts, etc.
What I am working on finding now is a way to attach a switch to that fuse and run it into the cabin so I can just flip a switch and know that the fuse is basically removed from the circuit. Overall, you would think with such a nice car, this wouldn't be such an issue. But I don't care removing a 25 cent fuse now and then instead of spending thousands of dollars.
I hope this helps all of you out there with the same problem. Mine is a 2003 Sedan.
My electronic wizard pal solved the battery drain problem by swapping two wires on the board, not replacing a diode.
If anyone has anymore info on this diode issue I would sure like to hear about it and investigate further.
