Hi Katta, I honestly can't tell anything about the mfd2 cos I have the other one (RNS510)
I really recommend that you buy the RNS510 though
(touchscreen,DVD,20-30-40GB HDD, Great Satnav, Bluetooth phone is amazing with the hardware, same with Reverse Camera etc,etc)
It's one of the best mods you could ever do to your car.
I love mine
