Yes its a working aerial just typeI would love to get a shark fin for mine too. Does it come with the electronics too?
Yes mate just open the rear hatch and theres a small peice at the back of the head liner that just pulls off (i did it) from the left then the right and it just came offWell.. It's just like an aerial extension cable it comes with because I think all the electronics You need is already ther in the lining of the roof, but havnt got the balls to take my roof lining off incase I can't get it back right :/
Mine is different to that cjrobbo, mine is more of a short pointy one than a long one, urs looks good tho, alot smarter than the standard aerial! Did You fit it urself?
