What kind of antenna do these things have? Is it that little cookie-sized disc I see mounted on trunks? Or is it more of a full antenna? Is it for GPS only, or does it take over as radio as well?
We all have tons of questions, don't we.
Sorry, it's just that none of the sites selling these ever go into the fine details like this. Always best to hear from real people with real experience, especially when they have the same car.
