avic-d1?

First off, i want to high-5 that guy that did the impala start-up screen change on his radio

(dont remember who it was or what subject it was under), that was badd @$$ !!

Maybe you can do something for me in either Chevrolet or a S-10 logo... i have paypal  !!!

The questions

question 1: im not connecting a DVD player to mine but i am getting the TV tuner kit for it, so will that bypass work or will i not have to worry about it because its not a RCA input, its a direct input cable??

question 2: do i have to spend $175 on the rear camera kit or can i use any, like the little one that fits into a key hole?

((still a RCA type connection ie, Ebay item: 5868814761))

Thanks guys...

~~waiting to get the newbie hazing~~
