One of the first things I wanted to do to my 2011 TE when I bought it in February was to replace the older non-JBL system with something newer. I dearly wished I could have kept those giant volume and tuning knobs, but they had to go in order to get CarPlay.
After a lot of research, I went with the Kenwood Excelon DMX905S. The Excelon units come very highly recommeded from my friends who know audio, and have a two year warranty, rather than one, which is nice support from Kenwood.
I had a local shop install the head unit, new speakers all around, and inner and outer sound dampening in the front doors. It wasn't cheap, but it sounds fantastic. CarPlay works great, and I only have two complaints about my choices and the install.
1. The Kenwood head unit is set up so that every time it connects to my phone, it starts playing music. That's pretty annoying, as I probably only have music on about 30-40% of the time, but I'm currently running navigation all the time, which means as soon as I start the car, and I'm getting ready to pull out and get on the road, music blasts out at whatever volume I had the navigation playing when I was last in the car. This is honestly kind of maddening, and I've been through all the layers with Crutchfield and Kenwood to try to stop it, with no luck. As much as I like the Kenwood unit, this makes me wish I'd gone with a different brand.
2. The shop that did the install didn't have the parts to make the USB connections from the back of the head unit integrated into the dash or console. They just sort of hang out below the AC controls. It's not great looking, but it gets the job done, and I can go back and clean it up later if I want to.
I went with the Scosche dash kit, as the silver matches the dash interior pretty much perfectly. I do wish I could have kept those big knobs, and it feels like a lot of wasted space on the dash, but I don't think it looks bad. Strangely, looking at the pics here after I uploaded them, it definitely looks more silver than the rest of the dash, but in person it's a great match.
Here's the link for that dash unit

I got the various adapters for steering wheel controls and auto integration, and everything works perfectly. The head unit could actually handle a lot of features that weren't included on the 2011.
