thanks guys.
@ john_o ill let you know how it goes. the Fiscon Unit uses the MDI port on the RNS. there is only one and i think the ipod connection uses that too. i do have an ipod in my car but i find it redundant now! the hard drive and SD feature rules out the ipod now. I only use the iPod in the gym/my bedroom amp now. which is great to be honest.
You can get the Skoda Bluetooth but as far as i am aware, the functionality is reduced from the FISCON. no fancy displays im lead to believe. the advantage of this, is it doesnt use the MDI slot. so you can run an ipod and the skoda bluetooth on the same unit.
i did consider the SKoda one, but i ruled it out because im happy with the HDD/SD for my music! ;)
