I love my new Tahoe. I have just under 1000 miles on it and, knock on wood, I haven't had any problems. I do, however, have a fine black dust that accumulates on the rear lift gate after driving it only a short distance. My Tahoe is white and it is really noticeable. It only covers the back lift gate/window, no where else on the vehicle. I don't know if it's exhaust or tire dust (if there is such a thing) or what. My other Tahoes never had this problem. If your car is any other color, it may not show up. It's discouraging to wash it and have it looking great and then drive for a few minutes and have the back looking dirty. Any ideas as to what this is or if it happens on anyone else's besides mine? On another note, I love that Chevy enclosed the wheel wells with the black plastic. They are so easily washed and kept spotlessly clean. This may seem funny, but it's something I totally appreciate and have never seen before.

I just found this on another site what a load of CRA* ............Thanks for the suggestion of calling Bose. It turned out to be the most knowledgable contact. I reached a very helpful support person at Bose Automotive group who really took ownership of the issue. She researched it and found something very disappointing. The Bose functions mentioned in the manual are not available on the Chevy Suburban, only on the GMC and Cadillac versions. The same is true for the Tahoe (only available on the Yukon and Escalade). The Bose system in the Suburban LTZ is a Bose 5000 which only has a four channel amplifier. Even though it's a "nine speaker system", the two speakers in the D-pillars (rear of the truck) are tied to the rear door speakers and the two speakers in the A-pillars (sides of the windshield) are tied to the front door speakers. Then there's a subwoofer in the center console. On the GMC and Cadillac versions, when you order the Bose system you get the Bose 6000 amplifier which is a true 7.1 amplifer (some speakers must still be tied together). It's only with the Bose 6000 that you get the extra DSP, Centerpoint and AudioPilot features. I asked whether the speakers were still all wired individually back to the amplifier but tied together at the connection. Then I felt I could convince GM to swap out the 5000 for the 6000 since the manual claims the Suburban has the features. She was pretty sure it was an entirely different wiring harness with the speaker tied together in the chassis and all that made it back to the amplifier were the four speaker connections. I have faxed copies of the relevant manual pages to Bose. They're very disturbed by what appears to be a mistake on Chevy's part, claiming certain Bose features are in the vehicle when they're not. The (navigation) manual, which is for the Chevy and GMC versions, simply states if you have the Bose speaker system, you have these features. Unfortunately it should qualify it to say not applicable in the Chevy Suburban (or Tahoe). My dealer, after reaching Engineering in Detroit, confirmed the very same information. I haven't been able to confirm it, but from what I can find on the web, only the Denali and Denali XL have the advanced Bose system (and probably the Escalade as well). Not the basic Yukon. The difference is that on the Yukon the option is described as "Bose premium 9-speaker system, with subwoofer in center console (UQA)" and on the Denali it's described as "Bose luxury 9-speaker system, with enhanced performance amplification, Audio Pilot noise reduction feature and subwoofer (UQA)". I guess it's the difference between Premium and Luxury. Interestingly, both the dealer and Bose asked me if I had ever experienced AudioPilot. I told them I hadn't but that it sounded pretty neat, automatically adjusting volume based on actual background noise rather than just based on speed (SCV). They both feltt that the basic SCV worked much better than AudioPilot and that AudioPilot was too subtle to hear the effects. The support person at Bose said they get a lot of complaints on AudioPilot from customers feeling that it's not working. So, I didn't get what I thought I was getting, but I might be better off. I'll keep you posted if I find anything else out. Until then, I'll just enjoy everything else the new truck brings us. Marc |

Replying to: jnrz (May 22, 2006 10:19 am) WOW!!! The new exhaust is on and it sounds awesome! Installation was a breeze (did it in my own garage and the Zoomer's packaging and instructions were great!) and the difference is notable right out of the gate! My computer is still learning what to do with the new found power, but it definitely seems to be staying in V-4 mode more and part throttle acceleration is notably enhanced! I will be taking it on a long rode trip next weekend, so I will get a better feel as to what impact it will have on the milage but right now I am VERY pleased!  (Hope to have some pictures available of the install this weekend) Have a great weekend guys! -- TuscoTodd '07 LT3

Replying to: jjmjgnx (Jun 16, 2006 4:37 am) Looks like your message got cut off - but to answer your questions... This is the Zoomers cat back system for the '07 Tahoe. (I think the part number is API-1015-07 if I am reading the invoice correctly). The system came with EVERYTHING needed for installation and after removing my factory exhaust, installation of this system took about 20 minutes start to finish! The system is set up where it uses all the factory rubber mounting points and fits like a glove with pleanty of clearance around suspension components, heat shields, etc! (Also included in the package were full installation instructions and also of note - the pieces were VERY well packaged!!) From the functionality side, I am definitely looking forward to seeing what type of an improvement it makes in the highway milage, but from what I have seen thus far, with it appearing to be staying in V-4 mode more, it should be notable!  Also - I do have to commend Zoomers on the fact that the system definitely lives up to their claim of no drone. I have noted NO drone or resonance at any speed/rpm, whether it is in V-4 or V-8 mode! This was one of the things that I researched prior to purchase and is part of what led me to choosing the Zoomers system over some of the others current available out there.  Needless to say, I am VERY happy with it so far! -- TuscoTodd '07 LT3

Replying to: tuscotodd (Jun 16, 2006 7:49 am) So, you haven't seen much difference in the way it sounds? I'm not looking for sound. I would like it to be about the same. I want to have a little more power, but what's most important is stay in V4 longer to get better MPG. I'm at about 17 now mixed, but I would like more.

Replying to: 2007yukonp (Jun 16, 2006 12:16 am)  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? Marc
