yeah gives you GPS if you buy a module to plug in at the rear. rip out factory one.
got my reverse camera hooked up, sits inside the car just below the break light on the back window. at night no so good, going to get it put into the spoiler at some stage. i got it hooked up to a constant power supply so when the boot is fully loaded, and i can use the camera and a rear view mirror
iPod connection, digital camera connection, USB connection. can run 2 option screens, and havs 3xRCA. pretty sure if can run tv also, i remember wanting to get one so i guess it would otherwise i wouldn't
of thought about it, but their not cheap :S
