I had to go to work at 2 AM today and noticed some de-icer had been applied to the road and there was a bit of icy sheen. I looked at my mirror display to check the temp and saw it was 35 degrees, but then it said "Ice" and went back to temp. It did this a few times then stopped and just displayed temp and there was no more ice on the road. I had no idea my Denali had this feature! I assume it used a combo of temp and traction control to diagnose the condition.

Afaik it's just a temp thing. Mine will do it when I fire it up and it's sitting in the driveway. Close to 32 there could possibly still be ice, so it flashes the warning.

Interesting to me is it only showed it when there was ice even though the temp was 35, and down the road it was still 35 but the ice wasn't on the road anymore and it stopped the warning. Also strange is I've never seen it although I'm always checking the temp especially when it's cold. Maybe I'm just not that observant after all.

Bypass as in you rewired all that back together?
No, I threw in a jump seat from the nnbs trucks and i had no place to put the controls so it was just sitting in the floorboard. I wired the rear negative input to the positive output and vice versa for both sides in the wiring harness itself. not too difficult, just a matter of trial and error. I tucked the rest of the harness up in the dash and called it a day.

Do you have a pic of the jump seat?

I finally got around to replacing the stock sub. Got a pioneer 8" shallow-mount and it sounds great...when it isn't skipping. I had to have a new amp installed since the Bose system was bypassed with the new head unit, so I'm hoping that's not the source of the problem. Back to the shop in the AM :(
