How do u use antinavi chip for MMBN2

it only works when you play someone in two player mode with a link, you can use it as an advance though
here is IS:
Darkness
BassV3
AntiNaviX
Fire/Aqua/Elec/Wood GSPL X

If you link and use it then it comes up as ???? (just like the other anti-\'s) and when your opponent uses a navi chip it will trigger and your opponent loses the chip and you use it (automaticly not like you can choose when)
