What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Getting an alignment done. HATE sitting around waiting. Hoping they don’t try and pull some bs about can’t get it into spec with my modest drop.

I’ve programmed new remotes with remote start capability for each of the twins. I’ve done the lock then press and hold on the start buttons. Both twins are responding by flashing the parking lights. I’m guessing there is some additional toggle that has to be flipped to get the functionality turned on. Both have the AP8 remote start capable option.

if there is a cel light on then autostart will not work

You hit lock twice, right?

No. I hadn’t seen anything that said twice. I’ll try it.

Shouldn't have to. Lock button once then hold the circle arrow for 2-4 seconds.
