Cons to replacing the stereo HU?

Hi all.
Thinking in replacing the HD unit in my 17 TRD Sport double cab with this Alpine iLX-F309 .
Seems to be able to keep all the factory options but just wanted to make sure I’m not forgetting something.
I don’t use the service records feature.

TIA.

 

Other than easily retaining factory microphone for bluetooth. It can be done but requires work, only reason I haven't replaced mine with my android auto son y head unit, I don't want to add a microphone, and too lazy so far to require he factory one.

 

Thanks for the reply. Where is the factory microphone anyways? Lol.
I don’t want to loose that either. And if I do have it installed. I’m planning in having it professionally done.

 

It's in the overhead console, looks like small vent
