Correct, there isn't a ultimate package anymore because of the RES. Everything is exactly the same between both packages except for the RES. Because of everything going on with chip shortages and supply chain issues, GMC has pulled the RES from production for at least the remaining model year. We might see it back again for 2023 if things start to rebound.Sounds like it was just added a couple weeks ago. I am seeing on the GM website that there is no longer an Ultimate package? So Reserve must have replaced the Ultimate and you have to a la carte the rear entertainment? Interesting change for mid-model year...
