I think Tune-it is dead. No option on the new Head Unit.
As I noted in the original post the Alpine does everything I need. Not having HD Radio was the only draw back but for an extra $100+ it wasn't worth it when I can digital radio feeds of just about every station in the nation another way. Yes, you can add the amp to all Alpine units however this is the one you can add it to and still be smaller than almost all other double Din's. That was a driving factor because I didn't want to find another place to mount the amp if I thought I needed it.
If I have a USB connection I'd never use Bluetooth for audio. I installed a USB outlet in the dash (next to the rocker switches for the lockers) and just connect when I get in the Jeep. My phone is a 128GB model so I have all of my downloaded music there and then I also use Spotify, iHeart etc. for additional content.
BTW....What's a CD?....
Wow, Tune-It never made it. It was a neat platform when I had my Alpine CDE-153, I even remember that model. I sold it on this forum years ago.
Do you have an digital radio app on your phone that you plug into the USB?
I did something similar to you for the rocker switch. Came out okay...works 100%, wish I could have made it cleaner.
