The reason why the digital disks are 12 cm is that Philips and Sony were negotiating to set the standard and, while Philips wanted 7" disks, Sony wanted 4.xx" since a lot of their sales were aimed at the car market. No reason why you can't slip a CD player into where your (uugghhhh!!) 8-track player used to be (wash my mouth out!).
