I recently purchased a 2010 Accent that has no radio installed. I purchased a Hyundai OEM radio. While installing it I found the wiring harness and the antenna cable. The radio has 2 ports on the back, a small gray one for the FM antenna and a round, yellow one for the XM antenna, but I cannot locate the antenna cable for the XM. Do I have to install another antenna and cable to get XM signals or does the antenna that is already installed get both FM and XM signals?

 

I purchased this car used. The previous owner cut off the factory antenna cable connector and replaced it with a crimp-on Motorola male connector for an non-XM aftermarket radio. I have installed a Hyundai factory XM radio with a curry (yellow) antenna cable port on the back, but don't know how to connect the factory antenna cable to the new radio. I guess I need to either get a new antenna or crimp a new curry Fakra connector to the factory antenna cable, but I don't know how to install a crimp-on connector onto the factory antenna cable. can anybody tell me where I can learn to do this?
Thank you
