Hello guys ! Have not heard much about this issue for a while now.I have to tell you something i've found out recently. I was at my local chevy dealership to visit some friends that i have made in the past year.So while i was there i went out to the lot and found a 2007 impala ltz with the bose audio system.For the heck of it ,i went and asked my salesman if i could try the radio out and see if it any better on the 2007 model year.Much to my surprise, it was extremely quiet with almost no noticable hiss at all !It seems to me the g.m. has finally addressed the noise issue with the head unit manufacturer and resolved it ! Its too bad that they did not do this on the 2006 models.All the controls are the same as my 2006 model,but much,much, quieter than mine even with the revised amp and software update that was installed in july! Just wanted to let you know this. Well, talk to you later. Pete.

So, you're saying that with the new amp in your '06, the '07 has less hiss...but it's still there? That's a bit odd. Maybe take a look at the amp used the next time you visit to see if it's different than the new amp we were provided. (It's located between the rear deck speakers, viewable in the trunk).
As for my car, I consider the issue resolved although I still take issue with the overall performance of the stereo as a whole. Had I not assumed a "BOSE" system would be premium and actually tested it, I would not have paid the extra money for it. It was a "live and learn" moment for me.

If anyone could answer this I would appreciate it.
I have a 2002 Impala with a trunk mounted AMP and 4 speakers but my 2006 does not have a trunk mounted AMP but I have 6 speakers in this car. Needless to say, there is a huge difference between the volume of the two cars and I would like to pump up the volume of my 2006.
Can I readily mount a GM (manufacturers) provided AMP in my 2006, is the wiring present to just to plug and play?
So to speak!

I'm sorry! I forgot to mention that i did in fact look at the amp mounted on the decklid in the trunk.I may be wrong about this, but it sure looks like the original amp that came with the vehicle when i had purchased it in Nov. 2006.Its definitely not the same as the one currently installed in my vehicle when i had the new design (revised) amp installed, along with the software update per tsb that was issued sometime this past summer.What i am saying is that G.M. has finally resolved the hiss issue with the manufacturer of the head unit, where the problem stemmed from all the time.After people started to complain in mass numbers about this problem on the 2006 models,G.M. then went to Bose to try to reduce this problem.Since Bose only supplys the amp and the speakers, they then did what they could to compress the output signal to a point that it would help the hiss, but not resolve the issue.It is sort of a band aid, if you will, but not a fix whatsoever!Whether or not the 2006 radio was not compatible with the on-star system, or it was just a sub-par head unit and the output signal was just not good enough, we will never know. I don't see G.M. ever admitting that they knew there was a problem, but did not address it before the vehicles were assembled.I do know for a fact that the 2007 models have a much cleaner sounding system, and just because we purchased 2006 models that we should not enjoy the same clarity!Beyond that i do not know what we can do about this.Mabye if we complain in large enough numbers, they will possibly consider upgrading us to the 2007 system,that would be my idea of the fair thing to do.My experiance with the new amp that is installed reduced my hiss by about 50% at most! I feel that is not acceptable, since we ( the consumers ),paid the extra money for the upgraded audio system that we should get what we paid for.Anyway,thats my gripe! I'll be looking forward to hearing from anyone who feels the same way that i do! Talk to later, Pete.

Thanks for the follow-up, Pete. I'll be taking my car to the dealer soon and will see if I can compare an '07 to mine. If it was the head unit all along, I agree that they should do the right thing and help us out...but I won't hold my breath.
#1377 of 1569 2006 2LT XM radio, MP3 questions
Dec 13, 2006 (10:40 pm)
My car currently has around 12,000 miles on it. I swear the sound quality of the audio system (the plain jane system - NOT Bose) is getting better. It's as if the speakers are finally starting to break in. It still can't compare to my old 2001 Impala, but it seems to be getting better.
Anyway, I know this is a stupid question, but how can I tell if I have XM radio capability? Also, in order to use my MP3 player, what do I have to do? Get a particular cord and hook it up through the auxiliary input?
I realize these are stupid questions, so thanks in advance!

To determine if you have XM, you should be able to press the "Band" button and cycle through AM/FM/XM. Even if you don't subscribe, XM channel 1 would play. It's gives information on how to register your radio and lots of commercials telling you how great XM is.
I believe the XM equipped radios also play MP3 CDs but I'm going to assume you don't have it. For the input cable, you can buy a male to male cord just about anywhere. Just make sure it's a stereo cable and fits in your MP3 player. A while back, a reader posted a link on here to an internet site that sold a retractable cord that allowed you to select the appropriate length and then quickly store it away when not used; check out post 1951 in the 2006+ forum.

Also vehicle equipped with XM should have XM antenna on the roof.

Aside from the rental fleet, all Impalas come standard with OnStar and now that the OnStar and XM antennas are integrated, all Impalas have the antenna in place regardless of whether or not the XM head unit is in the car. My nephew's 2LT has the antenna but no XM.
#1381 of 1569 Aux. Switched power
Dec 18, 2006 (3:38 pm)
I just bought a 06 Impala and am in the process of installing my various electronic toys. I can't find a source of switched power in the vicinity of the radio. (Actually, I haven't found it anywhere yet) Does anyone know of a good location to pull switched power?
