Times must have changed at Bose since the '02 TrailBlazer came out. Mine had a Bose system that had an "Auto Volume" function that sampled the interior noise level and adjusted the volume to match the original level. Never worked. Chevy replaced the head unit to no avail and then told me it was working as good as it could. (which was imperceptible). Bose told the service tech that the amplifier max input for this function was 30 millivolts. He measured the microphone output and it was 30 millivolts. This means the ampl was always saturated and couldn't function as intended. I suspect Chevy substituted a cheap mike for the one Bose spec'd. Tried to contact Bose to no avail. My 2007 Tahoe has SCV and at least it actually varies the volume level. Honda used to have (and maybe still does) a auto-volume system that detects cabin noise level. Do not have personal experience or know who makes it but I'll bet it works. Good luck! Let us know what you find out. Does this mean my Tahoe doesn't have the subwoofer?

Was there any noticeable sound level change at idle, part throttle, and full throttle? Did you buy direct from Zoomers or somewhere else? The picture on their website looks like you have to cut existing system behind flex joint and then clamp it. Is that accurate? Thanks.

I hope your Bose Amp is not the same one they put in the new Impala. They had to put out TSB about replacing the Bose Amp for being "hissy".
 
Does your 07 Audio system has Bose amp option? If not, the SVC is done by the Head unit

Supposedly the Bose 9 speaker system (incl subwoofer) is standard on the LTZ. I sure don't know where the subwoofer is. If it's in the console, it's well hidden. As far as my 02 TrailBlazer goes, the Bose system in it worked and sounded very good. Just the Autovolume didn't work.

Does your truck have a center speaker on the top of the dash? I'm thinking that might be an essential part of the centerpoint marketing? My 07 Denali has the center speaker and I do have various sound fields I can access such as driver, surround, back and so on. I do have audiopilot and it seems to work fine without issue.
 
Do you have any of the same functions/setup?

No center speaker. Appears to be 2 tweaters in the A-pillars, 4 speakers in the doors, and 2 speakers in the rear corners (D-pillars ?). So maybe there is a subwoofer hidden somewhere. I realize you can put one anywhere as lo-freq sound will travel thru things but on the subwoofers I've seen in home entertainment systems always have a grill opening.

07denali,
Just to let you know I bought a 2007 Tahoe LTZ maxed out.It has the premium Bose system with Nav & rear entertainment.I was told when I bought it that it had the Bose Digital Signal Processing system with Center Point.I have not been able to access it.I know how to access it but it's not there.No one at the dealer can answer the question why. Also Chevrolet has not been much help.
 One person at the dealer told me that it was incorperated in the nav dvd and that the next generation of dvd's would have it on them.(Far fetched but all I have to go with)
If any one could help it would be appreciated.If anyone that has the Bose DSP could read the actual part number off the Dvd and post it that also might help.
               Thanks to all
                    Ron

Sub/Centerstage by 07denali

The sub is in the floor center console of my Denali, you can easily zone in on it by turning the bass up and fading to the rear speakers but leave it one notch from being all the way back, the bass will still come from the center console.
 
Ron, I can only guess center point is part of the denali/escalade system with the center speaker on the dash, it makes the soundstage sound like it's in coming from the center vs the doors. Ithink I access it by selecting the "surround" soundfield.

Re: Rear window L trim moulding [sjenkinzz] by hpdc

I have a 2007 Tahoe LTZ on order, and stopped by two dealerships in Dallas and Amarillo this weekend to refresh my memory. I was really ticked to find that 8 out of 10 had loose L trim mouldings on the rear doors, many with broken or poorly fitting tabs. The remainder could be easily peeled off with my fingers (a little glue had been added to the top portion to tack it down). I probably upset some salesmen, but this is clearly a design defect and reflects lousey quality control. $49K+ would seem to me to buy a vehicle equal to any European or Japanese SUV. This may be a deal-killer for me. I think attention to detail is crucial. Does anyone know if GM is taking the issue seriously, or is that the best they can do? Will this be a festering sore to new owners? Who do we contact at the GM plant in Arlington to ensure that our vehicles don't have the same problem?
