Let them diagnose it. If it's covered by warranty they shouldn't charge you anything.

 

ok so thats what i did.

lets see what happens.

and i have searched this forum and looks like this is a rare case

 

i was sure it was covered for 6 years ?

Thats what i thought

 

Did you try disconnecting the battery for 2 hours? try that. I had the same problem.

 

yes i did...what do i tell services its under warranty?

 

Bumper to bumper is 3 years/ 36K miles.....what year is your car and when was it purchased?

 

my car is an 09 with a 11/08 service date but gilly they extended the head unit to 6years/unlimited mileage

 

They have to make sure they cover their techs time spent working on your vehicle. If it is the head unit, the warranty extension will cover all costs. If they try charging you for the head unit I would remind them about the extension.

 

Best of luck. Keep me posted

 

I would be a little upset if I was the owner of the other car and my amp was used to help diagnose (I guess it could have been a car they had for sale). If there was a short that blew the amp they could have blown the other cars amp.

It would be so easy to see if the preamp signal was being inputted to the amp and if it was and no output then move forward with the assumption that the Amp was faulty.

I've heard and seen this a couple of times and generally it has been a configuration issue or an issue with the head unit. In both cases it should be covered by the extended warranty that Nissan issued. If the Amp is fine there really isn't much else it could be.

When you tried adjusting the vol did the screen show the volume indicator but no sound? or did the vol indicator not even show?

your right when i saw that i was like WTF.LOL but at least they found out my amp was not faulty,it was working fine couple weeks ago what do you think it can be your the expert?

 

There was a thread sometime ago abt something along these lines, though I am not a hundred percent sure. I hope things are fixed in due course and with minimal headache.

 

new message from services ??::: I was just checking on this warranty extension, and found that the extension is limited to the head unit only. This is the face plate f where the buttons and controls are. This is a separate part than the actual radio. My tech will swap this part with the other GTR that I have here to confirm whether or not this is the problem. If the problem still persists after this, then I know for sure that the part on the extension is not at fault and warranty will not cover the repair. I will let you know once this is done, then you can decide if you would like me to continue with the search. With electronics, it is very difficult to tell how long the diagnostics will be. I have my best guy on the job. Will let you know shortly what the test reveal.

thanks

 

im confused from this?isnt the radio part of the head unit?

 

if they dont fix my car and fast im done with this dealer,i even had to pay 35$ a day for a POS sentra the car has 1900 km and it feels has if it going to fall in pieces

 

Technically speaking, the amp, wiring harness, radio is seperate from the Head Unit as technically that just refers to the screen interface...

However this exact thing happened to me about 8 months ago, I faught with the nissan dealer to make sure it was covered, however they weren't even aware of the extended warranty, which lead to myself calling nissan canada (have a contact pretty high up back from the steering lock issue i had in 09) thus I was called and told it would be fixed, in the end i didn't end up paying a penny and i had to get a whole new radio unit. Do you have a Cobb? there should be a code thrown for the issue

^you should not be paying for the rental car either as the manual clearly states one will be provided, I even had one for a few weeks free of charge while they were diagnosing the problem

 

thanks michael and they say because my GTR is usdm bought in californina im not entitled to a loaner?
also do you know what was the part they swapped to get your sound back?

i do have a cobb but no code thrown?

 

Can I call you? I don't buy the control issues because the controls on the AC unit communicate with the AV unit separately to the controls on the steering wheel. Therefore if neither work it is not the controls.

Also you said the volume indication was working which means the AV unit is getting the signal.

yea you can call me,im waiting on what there gonna,say and go from there

but all the controls and everything works perfectly minus the sound,car only has 22kmiles and never been tampered with

thanks for your help bryan

 

No problem, let me know if I can help.

Basically the summary is the AV unit is a single sealed unit (as far as Nissan is concerned) that is getting the signal/instruction to turn the volume up or down and is acknowledging that via the graphics on the screen. If the Amp is fine(see comment below though) then the problem has to be be the head unit and I have seen two different resolutions:
1) The software configuration needs resetting with Consult
2) The head unit is faulty.

One other thing they should check is the power to the AMP. If the issue is no power to the AMP then swapping the amp wouldn't help because the AMP would be fine, just not getting power. Of course if they checked the preamp out of the head unit and it was there then they would know the issue was with Amp or power to amp.

 

i hope you dont mind i quoted you and emailed it to the service adviser im dealing with

thanks again

 

franky i'll try and dig it up somewhere I have his contact info...

my issue was throwing a code on the cobb and it seemed like there was a faulty ground somewhere which was short circutting the unit and resulting in the lack of audio, so I don't know exactly what they replaced, I just know I got a new radio (i could only tell because the sat radio ID changed)

 

ok thanks

 

new email ffrom service they say the head unit is not at fault and now they want to start charging me $$$$$ to diagnose,bryan if its not the head unit or amp what else could it be?
thanks

message from service
the GTR tech already checked the power to the amp and the amp itself, i checked all the fuses and I also swapped the head unit with one that I know works and still the problem persists. The head unit that is covered is only the face of the radio with the buttons and controls, when you press the buttons you can see that the controls are working but that there is just no sound. I can scan a picture of the part that is still covered, but I can guarantee that this is not the problem with the system.)

he wanted me to contact you after he confirmed that it isn't the head unit. So if you would like me to continue I will have him keep checking, and ill let you know as soon I have news. At this point tho, I just don't know how long it will be.....

 

i told them if its not the head unit or the amp then im coming to pick up my car...So no sound for me

 

it happened to me once, all I did was just shut the car off and it went back to normal.
There is also a recall on the head unit, not sure if this is regarding that.

 

i tried the reset but i did not work,i will try again,

and they say the head unit is fine because they swapped it with another one and the problem is still there

 

I know it sucks but I would let them diagnose and fix the car....bottom line is as with any other car things go wrong that are out of warranty and we gotta pay for it.....you can try to bring it to another dealer and start from scratch but my guess is that you'll be at the same position you are now, unless of course you don't trust them that its's not the head unit....many of the early cars are coming out of warranty and we'll start seeing more and more posts about things going wrong and having to pay, it's just the nature of owning a car.....best of luck in a resolution

 

yea but sound in a car,it should not be hard to diagnose

 

Swapping the main AV unit (the bit with the DVD/CD drive in it) is not that quick to remove and if they were swapping from another car they would have to have dismantled that car also. The AMP I could see swapping to diagnose but not the AV unit.

Can you get them to clarify what they think is the head unit that they are referring to? I know it sounds silly but it isn't the panel with the controls and it isn't the screen we are talking about the brain on the AV unit.

 

Did you try the onboard diagnostic function? It seems that mechanic does not follow the service manual..!? Ask him if he did.

 

just wondering, how do you get to that screen?

 

• 
  1.Start the engine.

• 
  2.Turn the audio system OFF.

3.Turn the "VOL" dial either clockwise or counterclockwise for 40 clicks or more while pressing the "SETTING" button. (Beep sounds when starting the self-diagnosis mode.) Press the "BACK" switch and the initial system screen will be shown.

4.The trouble diagnosis initial screen is displayed, and then the items of "Self Diagnosis" and "Confirmation/Adjustment" can be selected.

ok thanks and do you know what i should look for when i get in there?thanks

 

before my sound went out completely

i remember the sound would have a mind of its own it would go really loud then back to normal etc when adjusting volume,im starting to think that something got so hot from parking in my garage and forgot to open the window a couple times

 

Seeing the other thread about the trim they scratched I think it is important to have the exact language of the extended warranty notification.

"Nissan has decided to extend the warranty of Instrument cluster assembly and Audio Head Unit " The audio head unit is the unit that has the DVD/CD drive, the Multi Function Display (MFD) actually has no audio capabilities what so ever. It does display information about the audio system along with gauges navigation system etc but you certainly wouldn't refer to it as the "Audio head unit".

My guess is they swapped the screen (need to remove the trim they scratched) to do that
and
The Amp which is under the seat

I would call the hotline at this point, unless you want to call them in the morning and ask them to clarify what exactly they tried to swap.

 

they swapped the head unit and amp only,, i dont believe they touched the screen but check with them tomorrow to make sure,they said everything is working perfectly but no sound head unit and amp working ok is there quote.
thanks again bryan for all your help!!
it might take a couple weeks even months but believe you me nagtroc where going to get to the bottom of this audio problem.

good night

 

I have this problem also for a few weeks now. Hope we can pin point which is exactly cover under the extender warranty.

 

Where are you located? I will gladly help diagnose the problem for free and document the findings on here for everyone else, but obviously need access to a car with the issue.
