I went with Kenwood with no complaints, and cooperated a Sirius receiver and Apple Play and Bluetooth.

Remember do it right the first time.

Part of me wants to go all out: Buy a new phone with wireless AA/ACP compatibility, and then go with the Kenwood.

On my Kenwood the front comes on with the button and for about 10 seconds after I shift out of reverse. It is nice for parking.

Do it. You won't regret it.

My concern about the Kenwood is its style. It looks like the buttons and animations glow different colors and are a bit "showy"... Sony looks so clean!

With mine I can control the colors it shows as well as the angle of the screen. From my experience, Sony and Alpine are both subpar to Kenwood quality. I've used all 3 over the past 10 years, and Kenwood has outperformed in every instance.

What did you hook up the power for the front and rear cameras?

I have the DNX994, I called Crutchfield about powering up the cameras and they had me cut 2 wires behind the unit and splice the camera power/ground into them. Works fine, no problems at all. I've read that some folks splice into the back up light wire in the rear of the car...

I think I'm better off with my base model radio and the 3.5mm Bluetooth module. I can get directions, answer and talk on the phone and toggle music forward and back off my phone now. For $10 I'll keep it all stock OEM.

I removed that plug and put a dual USB port in that space, I bought one from Crutchfield and it fit perfectly in there. For 12V power I just kept the plug in the dash behind that lower door...

Yes. It's easy. I have 2 USB cables and a 3.5mm jack in my center console (and a Vitesse Throttle controller). Just trim the bottom of the console. I can take a pic if you need.

I went with the Alpine you have listed. Go through Crutchfield and use the pre-wired service. Worth the $25.

That really isn't the case. I barely notice them glowing. The writing (the illuminated part) is very small.
