new 2010 prerunner need Double Din head unit

Hello everyone,

Monday I am getting a new 2010 metallica Grey Prerunner SR5. I want to put a new head unit in it right away.

What would you guys recommend in a double din touchscreen headunit with navigation (I can't find my ass with both hands). I have an iphone as well so I need compatability with it. I've done some online research but to me opinions are more valuable on a forum like this from people that have actually spent time with a unit as opposed to some online review just trying to sell units.

I would hopefully like it to plug into existing stock harness although it's not the end of the world if it doesn't. Also be compatable with the steering wheel controls. Do the sorcshe trim kits work with 2010?

Thanks
