Best double din radio

Hey all, I have a 4th gen 4runner suv, and I want to upgrade the sound as its my road trip car, I've been searching for a double din radio that has high quailty sound, has backup camera capability, and can play my cds and music from my ipod, also preferebly has bluetooth, in case I do want to connect my phone, but having my phone connect is not as important. I don't need apple carplay, or my phone to connect to it all, (but those would be nice for when my mom or sister drive my car)
At some point I also want to overhaul the speakers/tweeters, and add a sub woofer.
Thanks in advanced!
