Gm pickup truck radios, with the exception of the S10, have not had switched power at them since 2002. they use a data bus to tell the radio when to turn on. I believe all fuses in the dash fuse panel are constant power. Check for an empty 6 or 8 pin plug in the distribution center to the left of your brake pedal. one of the pins in there will test as an accessory, just be sure to add your own fuse holder, most radar detectors are likely fused at 3 amps or less. Hope this helps you.

Alright, I was finally was able to dedicate some time to this. Thank you Lunatic, that was the soltion I was looking for! Under that distribution power's cover, there in fact IS an empty 6 pin plug. I tested those exposed plug pins with my multimeter and that is a clean 12V supply. The far left side (2 pins vertically) are both switched on the ignition so it was real easy to grab that power lead. Wired it up, turned on the ignition and have success!
The radar detector power whip I purchased from Whistler a few years back already has a 3A fuse built in.....and is absolutely neccesary!
I hope other users are able to have such an easy wiring job with this knowledge.

That's good to know, thanks for posting up what you found out. It doesn't make sense to me that none of the interior fuses are on switched power, but I'll leave that up to the engineers at GM. Like I said, I've pulled switched power from the main fuse box, but that's all. Hope I didn't cause you to waste too much time looking in the wrong place. At least now we know.-Sal
