That's what I'm on, I haven't received any 6.X updates.Everytime I see a new feature or improvement worth updating my truck for, I see a thread like this showing the new software updates are riddled with serious issues and I'm back to hanging on and chilling at 4.1.3
Well I'm sure I could get updates if I wanted, but I have updates switched off and my TCU disconnected so, no updates unless I say so lolThat's what I'm on, I haven't received any 6.X updates.
