Are the 2012+ stock radios an easy transfer to the 2005 dash?

I have a 2005 PreRunner and I'd love to be able to pair my phone to my radio. If I got a Bluetooth-enabled radio from a 2012+ Tacoma along with the necessary dashboard moldings, would the connectors and steering wheel controls all work together without fiddling with wiring or harnesses? Bonus question: Where is the aux input on 2nd gen Tacomas (I see the button but can't see the aux jack in pics like this)?

I'm asking because I'd really like to pull this off while having a stock look with zero actual electrical work. I don't want to have to deal with wiring, harnesses, extra microphones, etc. I just want a stock look with modern phone call functionality. Is this possible?

Edit: If necessary, an exception to the above is that I'd be able to run the wires for the aux input location.

 

Search my name, I made a DIY thread to retrofit a newer radio into an older truck.

 

@steveo27 Thanks, that's quite the writeup!

 

Thanks. Hope it helps.
