Have you asked the dealership. It might just be a mis-fitting item that will take them a few minutes to fix.

This comes way too late for rwerner, but it may clear up any confusion. I'm familiar with all of the Bose automotive amplifiers because I'm an EE for the company. The amp used in the Tahoe is assigned to a team of engineers of which I belong to. The Tahoe does not have CenterPoint but the amplifier does employ digital signal processing (DSP). The amp in the Tahoe is a 5000 series amp. We assign project names to most of our amp designs at rollout which are used internally to easily identify them. The amp in the Tahoe is referred to as "Lugnut". As with all of our amps, each vehicle model's interior is EQ'd with complex microphones resulting in a EQ curve that is loaded into the amp's processor each time the system is powered up. The more complex amps actually use a different EQ for cloth versus leather interiors. Because so many things can be tweaked to the signal in the digital realm, analog signals are passed through analog to digital converters, or CODEC's as they are known. After processing is complete, the signal is passed back thru the CODEC's where it's sent to the final power amplifiers. The CenterPoint feature found in the Yukon Denali, as well as AudioPilot use a completely different amplifier (a 6000 amp), and consequently a totally different wiring harness. While it's possible to retrofit the Tahoe with the 6000 amp, it would require the removal of many interior components. I would imagine that GM would balk at performing such a request.

Exact same model and build month here on my LTZ and exact same problem. Truck is tight as a drum everywhere else. Must have been a problem on the line. I hope they come out with a TSB fix because I would hate for the dealer to have to tear apart the entire headliner and start doing exploritory surgery on my brand new baby.

This happened to me once on the front. The dealer looked it up and showed me a bulletin that said when the heated washer fluid gets to hot this may happen.
I hope it's not a sign of a problem to come.

Vent Shades - Window Covers - Wind Deflectors
by csprick

Jan 28, 2007 (2:24 pm)

I'm seeking some advice from anyone who has installed side window covers/vent shades/wind deflectors (or whatever their real name is)on their Tahoe/Yukon.
Most of the local auto parts stores seem to not yet have any listed for the 2007 model, but do for 2006 and earlier. Will they fit OK?
Do they, in fact, allow you to crack the windows an inch or two and keep out the rain?
What kind are "best" - in-channel or the stick on above the window type?
Any recommendations by brand/manufacturer?
Do you notice an increase in wind noise after they are installed?
Any other comments or advice?
TIA.
Chuck

Chuck,
Have you checked the Weather Tech (URL Below)?
http://www.weathertech.com/store/vehsearch.asp?item_group_id=4&make_id=11&year_n- - o=2007&veh_id=150&veh_opt_choice_id=0
Its installed in the window channel rather than using 3M tape to the outside of the window frame. It does a nice job venting during a rainy day and keeping the wind noise down. However, I don't really care for the front D/P side shades as they are kinda in my view when I look out the windows and at the side rear view mirrors... at least that was my initial thought about the shades, but, I am now all used to that now. Good Luck!

Strange nav radio issue yesterday - radio muted

Out driving around and realized that since I had started it, the radio (w/ Nav) was muted. I did not have the mute button on, tried changing the station, figured it might have been an XM problem so switched over to FM. Not only did no sound come out, but the XM station name overwrote the FM station name. Pulled over, turned the car off, then back on, everything worked OK then. Anyone had this issue?

I had my '07 Denali in for a separate problem (confounded transmission woes at 600 miles!), and asked the service manager at the GMC dealer if they'd look into a squeak around the rear domelight, just where you describe. He mentioned that they'd had several complaints, and that he have the service tech put some "insulation" around the light, which should (and did) take care of the problem. Took about 2 minutes to alleviate the problem. Now if they could just get the transmission fixed!
