Gen 2.5 Entune Radio Headset work for 2007-2013 Tundras

Quick questions, So I really want to rear backup camera. Trying to look for good options to do that. I see that some folks are selling the 2.5 Gen Entune headset for cheap.

I was wondering if the 2.5 Gen Entune headset would work for the 2 Gen Tundra (2007-2013)?? Will it be a drop in? or will it take significant effort and any additional trip pieces needed for it to be installed? Would it also just be a plug and play? Do i need to get a specific backup camera for my truck (as I dont have one factory installed)? or any plug and play camera should work?

Also as I said really need it for the rear backup camera and radio.. maybe bluetooth if it enables that.. so would it work?

 

The dash and wiring are completely different between 2nd gen and 2.5 gen trucks.

 

Aaah dangit.. that sucks.
