What did i screw up???
I've just finished installing a Calibre K40 Radar/Laser detection system, and the following modules from KPTechnologies: Window Rollup, Sunroof Close, Shift Light, Navigation Bypass, and Traction Control Memory.
Now, I have the following 2 problems:
1) My Supplemental Air Bag Warning light constantly flashes
2) My instrument cluster lights reset to the dimmest setting each time I start the car, and it goes to the instantaneous fuel economy display
Any thoughts????

That is true, especially if you have an el-cheapo test light. Not that I advocate poking around, but if you do, you should use a good resistive test light that helps eliminate that danger.

I emailed Kevin Pierson from KP Technologies and he had the answer for the Airbag warning. It happens often from unplugging one of the plugs on the white plastic box on top of the radio unit.

THANK YOU KEVIN!!!
I do still have the dimming issue though. All settings are retained on the center display, even the brightness. It is just the brightness of the instrument cluster, and the fact that the stupid instantaneous mileage display keeps coming back.

too soon to tell, I just got it going last night, and I'm not finished. I have installed the front radar receiver under the front bumper and dual laser defusers on the front bumper. I still have to take off the rear bumper and put in the rear radar receiver and the single laser defuser on the license plate bracket. I've only driven to work and back with it.

So both of the remaining problems have to do with the cluster? Did you take the cluster out during any of the installs? I'm guessing once the car is running everything "works" again, but you just have to reset them?

Does disconnecting the battery do this? If so, then yes I have, many times.

did you ground everything to the same spot?
Sounds like some sort of short to me.
What your prob going to have to do, which is going to suck, is uninstall one thing at a time to see whats causing the prob.
You shouldnt install so many things in one shot like this, its better to do one thing, test the car out make sure its good, then move on to the next item.

Taking a look at the MWI.pdf file of the '08 G37 coupe service manual (that's the closest I have and seems to be in line with my '07 G35 sedan manual) both the driver information center and the illumination are controlled by both the BCM and the "Unified Meter and A/C Amp". The "Unified Meter and A/C Amp" is the white box on top of the radio brain. There are several fuses associated with the Unified Meter and the cluster, so I would start there first. I would also be paying extra attention looking out for anything else that doesn't work.
When you turn the headlights on does the cluster brightness automatically change?
Do your A/C (or heater) controls default to the same position (regardless of where you left them) each time?
If the fuses check out good I would pull the radio back out and inspect all the wires on the harnesses at the Unified Meter and A/C Amp. I would look for any jammed, bent, or broken pins inside the harness.

Stoof, Yes, I grounded everything in one place. I also ran a dedicated power wire from the battery for the things that needed 12V. I tapped directly into the fuse box (empty spots) for the things that needed Ignition. I don't like splicing into the factory wires unless I have to.
Kevin, I'll check all the fuses and I'll remove the radio again and check those plugs when I get a chance. I just wonder if there is some sort of weird/stupid reset procedure like the airbags.
I did notice that the brightness is maintained when the headlights are off, it is only when they are on that it always goes to the dimmest setting. Also, not only does the display reset to the simultaneous mileage, all the other displays on there get reset...trip A, trip B, average MPH, average Speed, Timer, etc. This is regardless of the headlights being on or off.

The reason I asked about the lights being turned on is because that is controlled by the BCM - it seems the BCM is functioning properly.
From your added details it definately sounds like the Unified amp and A/C meter is not getting power when the vehicle is off. I would be optomistic that it should be an easy fix (ie a blown fuse)
