I have a Multipla 100, 1.6 16v 1999. Its a nice practical car and looks great

I bought a scanner U480, but it says linking error. Then I bought a Kiwi Wifi interface and REV2 app for my iphone, but it connects only for 1-2 secs only to disconnet again. Now im thinking about using multiecuscan, but apparently there are 3 different adaptercables to choose from.. Witch one should I choose? Right now I think its K1, but not sure..
If I get the right cable, can I the use my scanner U480 or my Kiwi Wifi Interface?
