i have installed a few on different rides, as my 04 has both, depending on many factors on backup system,,are ya trying to add on audio system or a by itself, so easy if separate, get a wireless and simply add to reverse wire on back, look at 07 rear wire for tail light and it will show you. i have mine wired full time as i like seeing back there, dash cam is as simple as mounting on dash and plug in aux. and as far as wiring the reverse camera monitor you can mount in many locations but up by rear view mirror is my choice and run the wire to fuse box on a power feed for acc. the rear camera you can mount on lic plate frame. there are videos to watch i am sure but its pretty straight forward.
