mfd upgrade

[abdnmoh]

hey guyz,

Wondering if any1 can help.. Im getting an mfd fitted and want to watch stuff whilst on the move on it.

So far ive bought a plug and play wire and the gps antenna from ebay to make the satnav actually work.. I want to fit either a hdd (hard disk drive) or dvd player but prefer a hdd. What else will I need to make this work..?? Has anybody done it b4??
