Is there a "Plug and Play" radio unit easy to install?

Hi folks,

I'm not used to post around here and I would need some advice. I'm considering to install an aftermarket radio but I do not know which one is the best for me.

I know there are android and windows CE alternatives. I saw a lot of modification on this forum and I'm sorta lost to tell you the truth :/

What I would like is a radio unit which can connect to my smartphone to get internet and a simple installation. In fact, I just want to switch my radio and to keep everything working (wheel steering, back camera, etc...)

Am I dreaming or this solution actually exists?

Thx guys for your help
