It has nothing to do with the battery, it's the electronic steering in the Colorado. There are many discussions on this forum about it, search, I went through this same thing when I got mine in Feb. The owners manual says disconnect the battery during the tow setup. I don't plan to prove the checklist right or wrong. The RM-766 is not hard to install and is easy to use. I'm at ease having done it as I just don't need surprises with vehicles.
