The steering wheel controls all work when I use Carplay on my OEM radio in my CTS. My ATS doesn't have carplay.On MVI's site, the upgrade states: Is this a quark of doing the upgrade, or does the loss of steering wheel controls occur in factory delivered 2016 and 2017 vehicles too?
My experience with Opuradio went well however a friend of mine ordered 10 days ago and it still hasn't shipped and is being given the runaround. He's trying to cancel order but no reply.I have posted this in other threads but figured I would post here as another source. Mine was trying to store a station preset to the middle bottom of the screen and wasn't responsive to touch. It would sometimes work to touch and my steering controls would work just fine. I knew this was an overlay issue as I deal with that in my work of custom control systems for homes. I also have a long car audio background so it was an easy task for me to switch but not hard at all for the average guy. Just take your time and don't force anything. Mine has been working like it should for several months now. I would highly recommend going this route as the dealer wants $1500 to replace the stack with the same ol crap. Here is the link to China. This is as close to OEM as I could find. Was packed VERY well!
Another thought, make sure to seat the ribbon cable correctly. I had to pull the stack out a couple of times before I got it so don't loose hope if it doesn't work the first time. Take your time. Can't hurt to take pics as you go for reference.
