Of course, years later I replaced the head unit with an Avin Avant 4. Glad I did. Best upgrade I've made.

"1.) iBus App
-Is this only really needed if you want to retain your OBC information on the screen like Consumption 1, 2, Average Speed and so on?"

Yes, that's what it's for. I wouldn't not get it as it gives you more info available than the obc in the stock nav gives you. You can get the Deep OBD app and it can give you even more. In my opinion with the joke of a temp gauges we have the cost of the IBUS app and dongle alone is worth getting the IBUS for the accurate temp read out.

-I did a quick look on the iBus App website, basic OBC license plus USB module + shipping came out to be $83.00-ish. Thats like $40.00 cheaper vs Avin. I wouldn't mind waiting and saving myself $40.00.
-Do all the Avant 4 units come with the stuff to hook up iBus even after the fact? Or am I going to get screwed here by not getting the iBus through Avin?"

I got mine through Avin as I didn't want any finger pointing if sometihng went wrong.

"-Apple CarPlay = I kept reading the forums and pretty much I hear a mix. I hear if you go with "wired car play"...the charging is terrible. It charges your phone slower then the drain rate. Going wireless has its own set of things like you need to click multiple prompts to connect."

Bought it and used it briefly. It takes control of the unit and I didn't like it.
