Does my 2003 Toyota Corolla have a roof or glass antenna?

I have a new SkyFi3 (a Delphi XM satellie radio receiver) that came with SureConnect, which clips around the vehicle’s outside FM antenna and sends the FM signal along this wired route to the car’s FM antenna. XM states that this is not compatible with outside roof antennas but is compatible with glass antennas. I have heard conflicting info about what kind of antenna my 03 Corolla has- glass or roof (it looks like roof, but who knows). Does anyone know what kind of antenna this car has and if I will be able to use SureConnect with it? I have searched online, including in XM fan forums, and can’t find a definitive answer. Thank you!
