getting my car soon, hopefully it comes with an AUX jack since i hear the newer '07's did not then they made it standard, anyway
if i do have the jack i plug in my reciever in the there so the hookup is done there, now about the antenna connection is im not sure what i should do, those cars have antennas on back of the roof, so do i use the SIR antenna or do i splice into the car antenna, dont have a reciever yet, i will be getting i thinkg the newest sportster

thanks alot
