What size is the head unit?

I am looking to purchase an after market head unit for my 16 off road double cab with nav. What size should i be looking for? Does anyone have recommendations on them? Also does the back up camera hook up to aftermarket? I would like one that uses the google speech recognition technology because the stock is terrible and not even worth using!

 

Go to Crutchfield.com. They will have you enter your car information... with this they will show all head units that will fit, as well as automatically put the dash kit and all wiring harnesses that you need in your cart for you. And yes, your back-up cam will still work!

 

This.. i get all my gear from here. Im getting a 3800BHS pioneer this summer from them for my 2nd gen. The great thing is they send you all you need for the install (minus wire butts, Shrink tube and tools)
