Nissan Altima Audio Questions
2007 Nissan Altima 3.5 SL - Bose premium sound
For some reason the speakers hiss even when the stereo is off and even if the car is simply on accesory (ACC). Has anyone experienced the same annoying problem? Any help would be greatly appreciated.
I think it might be that the amp/preamp is powered on separately from the head unit - therefore sending a signal to the speakers when the car is powered on.

Not sure what to do.
Were you able to get this fixed?
After speaking with various car stereo installers, the consensus is that there is noise being generated by the more powerful amplifier that is installed with the Bose Premium Sound Package. Unfortunately, this upgraded amplifier (located on the underside of the rear decklid in the trunk) turns on using a different power source than the head unit. Therefore the amplifier is turned on once the accessories are activated, not in conjunction with the head unit.
Why the hissing? Nissan/Bose installed a powerful amp which has no noise gate (cut off) on the hissing noise until the head unit is activated. It's not there's anything wrong with the car (I wish because then I would have them fix it) - it was poorly designed. I believe it was an issue of cost/benefit. To have the amp and the head unit turn on together would be more costly (they would need to run more wires through the car and most Altimas are purchased WITHOUT the premium sound package.) The cheaper method is to simply tap into the power at the rear of the car when the upgraded stereo is installed.)
I have to assume that the hissing was an acceptable byproduct of this cost-cutting design. They could have installed a noise gate somewhere in the line to allow the hissing only when the head unit is powered on. Why not? I have no idea.
Scientific information about the hissing noise:
"All amplifiers generate a certain amount of electrical noise. Note: the noise I refer to here is noise inherent in semiconductor circuits , not noise caused by improper wiring, poor shielding, etc. Generally, the more powerful the amplifier, the more noise it will put out. If you turn on an amplifier (with the input device connected but powered off) and listen to a speaker connected to the amp you can clearly hear a hissing sound. This pretty much represents the noise floor of the amplifier. If the amp has an input level control you will likely notice that the noise may vary as a function of the setting of the control. For a powerful system, the noise might seem pretty obvious and annoying; however when actual music is playing the noise will be totally masked."
I think that last sentence wraps up Nissan's decision to leave the hissing. Most of the time, the car will be used while it is moving or when the stereo is on, or both, therefore reducing the time where the hiss can be heard (making it less of a problem - to them). The problem is that the car is so well insulated, I can still hear the hissing while driving around with the stereo off! Hopefully someone will get to the bottom of this soon.
Highly disappointed with sound - too much base and front door speakers sound
muddled. Thought front door speakers no good and went to dealer - listened to others and problem is the same. Great car horrible sound. Suggest in future anyone buy the normal(also lousy) system and then upgrade at an audio shop.
Once "stuck" with Bose then trying to replace system extremely expensive.
Have visited several audio stores - some say impossible to just replace front door speakers - other say you can do it. Need help from other dissappointed buyers
with same problem and best way to improve sound -
Correct me if I'm wrong, but doesn't that simply mean that your ipod will play through the stereo? I am assuming that you will have no control w/the stereo or "interface" with the ipod. Is that correct?
Does anyone use the aux and how well does it work?
Is there a way to get full integration and if so, is it worth the price?
Any extra integration with the Nav system? Ipod video, etc???
Thanks!!!!
{ Interface System for iPod®
Designed just for Nissan, this system connects via the Altima radio so you can listen to, control, and even charge your iPod, all while it's hidden in your glove compartment. (iPod not included.)
The stereo interface is compatible with any iPod equipped with a dock connector, Generation 3 and above. Be sure that your iPod is updated with the latest firmware
SAFETY NOTE: ALWAYS give your full attention to driving. Avoid operating your iPod in such a way that you can be distracted during vehicle operation. }
Unfortunately it doesn't list a price.....anyone actually have this feature? If so is it worth it? Will it integrate with the Nav too - video?
Just looking for some input from those who may be in the know as the sales rep I spoke to at the dealer didn't have too much to say about it.
Thanks!
it starts making funny noises, like the cd is skipping (although its not). it sounds like some wires are touching somewhere and it effects my front passenger and drivers side speakrs, and its been annoying me. i know i did not blow the speakers, bcuz i know how blown speakers sound... and if it would b blown, it would b permanent sound as i would turn on the music loud everytime. but the noises appear and disappear daily. i am scared (a little) to take it to the dealership, because i dnt want to pay any money for sum [non-permissible content removed] dat i didnt do... or will they fix it by warranty.? im confused someone plz help
I have the Bose stereo and do not have this issue.
How did you get Bose to come out and look at it?
As a last resort, any decent trim shop should be able to fix the loose roof panel, though you might have to pay out of pocket ....
It was not easy to get Bose to look at it. I contacted Bose over several emails. Then told Nissan I was in contact with Bose, and when I went to my appointment there was Bose rep there. He did the full sound check on it. Bose was very helpful, but Nissan acts like they want to help, but it's just a front.
The know exactly where the noise comes from, but unless it's "documentable" then they don't want to mess with it.
Sorry, but I don't understand what you mean by "documentable".
If the (1) Bose rep was there and heard the rattle, and (2) they know where the rattle is, and (3) they know how to service the roof liner, I don't understand why they won't take a stab at fixing it. This just doesn't appear to be that big of an issue.
Exactly what am I missing here?
Where/how far away is the next closest dealer? Have you tried them?
How far have you pushed this issue up the Nissan service structure?
Warranty work can be done by ANY authorized Nissan dealer.
Give another one a try and see what happens...Good Luck!
Do you have a sunroof? I have an 08 and the rattle was due to the headliner not being properly secured. I have the shop manual, and was able to locate the securing points. Once I re-attached the liner at the appropriate points, no more rattle...
I put a link to an on-line Altima manual a couple of months ago on one of these Altima forums, but I don't remember which one. If you want to take a few minutes, you can search it out and find out the link to it.
Good luck...
I have the Bose system with NAV, and I am very happy with it.
Have you gone to the Altima web-site and looked there? I'll check and see what info thay have on it...if any.
I'm not surprised that no one at the dealer knows anything about it...

The hook-up shown in the picture shows a standard iPod docking cable, so I would say my earlier post is correct.
I hope this helps...
I take my car in to get the iPod interface to be installed. Almost 4 hours on Friday, they say they're having difficulty and ask me if I can bring it back on Monday when they have a Nissan Tech there to help. I return Monday morning.
After not hearing from them all day, I call Monday afternoon to ask when I can pick it up. The response I get?
"Apparently the iPod interface doesn't work with the Nav system model, only the regular radio." - which is contrary to what I was told when I purchased the car. Honestly, it was my final selling point to BUY the car. I wanted an iPod interface I could control via the nav system - otherwise I would have gone with my other car choice...
I have read in another forum that, quote "theyre in the process of developing an ipod interface for the alty's with the nav system.....i cant wait for that....according to another member on here he talked to the people at Nissan and they said sometime in July." though that really doesn't tell me much - nor does the guy at my Altima dealership know anything of this interface...
I am beyond irrate right now. I just spent over $30k on a car for a specific set of features I wanted, was told I could get, and now am being told are not available...
Anyone have any information re: a potential interface for the nav system coming out?
Man, I feel your pain...been there, done that a couple of cars ago myself.
Your best bet is to try www.crutchfield.com and see if they have anything. If anyone will, it will be them, and they are extremely helpful. Get the phone # from the site and give a tech a call...
Good luck, and let me know what you find out...I have the same NAV system in my Altima.
The only reason I went for the Nissan Altima and not the Jetta was they said they'll match the ipod interface.
Now no one has a beastly idea on how to make it work with the nav system, some even tell you that you have to disconnect your cd changer and XM!!!
The aux input sucks!.
ANY NEW IDEAS? I AM RUNNING OUT OF PATIENCE.
..I was lied to...
Is there a cable in the car or am I to use a cable from apple? The radio has an external source plug, I assume that's where it would go? or is this all in the hidden compartment just in front of the gear shift, below radio?
I'd appreciate any help figuring it out...
Step 2) Ask them to hook it up.
hahaha
Sorry. Stupid joke.
The cable that connects to your iPod should have come with it, and comes out through the glove box. The connector plugs in to the external source plug on the back of the radio (I believe).
As the rest of this thread implies, I hope you don't have the navigation system otherwise you're about to run in to some serious (impassable) trouble.
I asked about it at the dealer and they said it was possible. I also researched it online and Nissan's own Web site talks about iPod compatibility. Nowhere does it say that this is not the case for NAV units.
I wish we could do a class action lawsuit or something. This is a major reason why I purchased the car, and had I known that the iPod integration wasn't possible, I would have purchased differently.
It's been over a year here...
-- "I have the Bose system with NAV, and I am very happy with it."
happy even with the hissing sound????
Does it come up immediately and let you browse by album, artist, title or playlist using the radio controls, and show the song information on the display?
I looked at a Ford Fusion first, because of the voice controlled Sync system, but when I plugged in my 80 GB iPod the Sync system indexed for over 10 minutes, then said it couldn't index everything (evidently I exceeded the capacity). But I also looked at Honda and was impressed how quickly the USB interface let me search using different criteria. If the Altima works that way I'll be happy. Unlike Ford and Honda, I can't find an Altima on the dealer's lot with the iPod USB feature already installed so they can demo it for me.
I have Bose without Nav, by the way.
The interface works ok, but it's a little difficult to figure out at first. The iPod has to be detached for the XM to work, but that's ok with me. Two things I don't like: (1) When you move from track to track you see the "channel" (track) number first instead of title information, because the radio "thinks" you're switching XM channels. But a second or two later the title (or artist, or whatever single piece of information you choose to display) appears. And (2) The iPod controls are disabled while it is connected. Some third party interfaces have a "hybrid" mode that lets you use the radio or iPod controls, whichever is faster for the search you're doing.
The USB interface in the low-end Hondas works better, and Ford's Sync works great (if you don't have too many songs), but this interface is ok and I really like my Altima coupe--especially now that I have a spoiler on it too!
