Does anyone happen to know what gauge these wires are? I am guessing 22 or 24?

Excuse my ignorance, but what would be the purpose of having a 2nd battery?

This is what frustrates me about the purchasing process. I was in my local dealer looking at a '15 Sierra a few days ago, and I specifically asked the salesman about updates, and he told me they were completely free. I asked because not only did our '08 Yukon require paid updates, but they were never available! As stupid as it sounds, the infotainment in these GMs has been my #1 excuse for holding out on a new vehicle for the past two years. The nav in that Yukon was just plain awful; the route it chose was often inefficient, gave us wrong directions a few times, and we were forced to use 6 year old maps towards the end. My wife's '14 Acadia is better, but still seems clunky to use. I don't know what to do. Mayble I'll just get a '15 and start shopping for aftermarket units that support Android Auto.
