Magician Navigation

Is Magician Navigation cannot be active on battle phase to negate magic/trap?

Here, i used magician navigation on enemy end phase to sp.summon 2 dark magician.so my Magician Navigaton in my Gy..on my next next turn n battle phase (onward) enemy active canadia n other trap on battle phase N I CANNOT USE MY MAGICIAN NAVIGATION to negate!!!

So my next question,what Speed Spell is Magician Navigation? Or Magican Navigation Cant be chain?OR magician Navigation Cannot be active on battle phase to negate? On duellink gamea Magician Navigation is Quick Effect,so i think its Speed Spell 2..
