is it possible to be able to run two back up cameras at once?

I am trying to install the avic-x910bt and the manual says to hook up to the parking brake with the light green wire. if i am doing the hard wire bypass do i have to still connect this wire? what is this wire used for? need help asap. thanks

what is the speed sense wire for? what is its actual purpose?

I am going to be buying an X910BT as soon as i find a good deal. I see all of the HUs on ebay that are really cheat they are 2009 edition of the model. but how do you know that the GPS is up to date? what are things i should look at when i am buying it?
