what size bit do i need to drill a hole for flush mount?

I believe the hole is 21mm. The front flange is 30mm.

Why does this come with two locking rings/nuts? One regular and one flanged...

You can use whichever one works for your application. You can also first use the flanged nut on the back, and then double up, using the one without the flange to lock it down so it doesn’t vibrate loose.

Does this work with head unit with apple carplay?

as long as your head unit/stereo deck has apple car play, it will work just fine.

Fantastic quality for price!

Absolutely fantastic cable, pretty decent quality for the price, and nice tight fit on the USB port. This made for a great input line for my aftermarket head unit.

コスパのいい商品です。

コスパはいいです。自分はあまり目立たない所にUSBポートを増設したかったので、こちらの商品で十分でした。スイッチパネルの空き部分に追加したいとかであれば、別の商品の方がいいかと思います。他の方のレビューにある固定のガタとかは、自分はあまり感じませんでした。
