• Can it be replaced easy? Does it have the same radio strength?
    I believe that on Navi 900 the radio antenna is integrated in the left side rear fixed window, and replacing a long antenna with shark fin will lower the radio signal :(

    I would like also to change the antenna that is standard for InteliLink R 4.0.

    On my Astra G , the long antenna was stolen after one month :(

  • Its easy. Just remove the C pillar trim, detach a little the headliner and its done. But I have no idea if the shark fin can fit with the normal antenna cable...
