couple of questions regarding the sterio in my 07 astra VXR

i would like to have a digital radio and some sort of ipod device other than the radio tunner jobbies or the expensive ciggaret lighter ones as i dont like clutter

is there a factory replacment for mine? or do i have to buy another head unit?

i have very little if any knowledge regarding ICE so to speak so your guys help would be appreciated
