A general couple of questions out to everyone really. I lost my aerial couple of weeks and thought I might as well go with a shark fin that i've been thinking about but a bin unsure on a few things. First, which shape is the correct OEM audi shape? There is a couple of after market ones but they seem a bit big or don't look right. Secondly, I don't have satnav, dab or any thing digital like that, so I assume just a normal shark fin aerial that has the normal connection will be fine for my A4 B5?
