Why install a new satellite radio antenna when there's already one on your roof? iDatalink's Maestro SAT1 cable allows you to connect your SiriusXM satellite radio tuner to your vehicle's original satellite radio antenna, eliminating a lot of time, heartache, and hassle. It adapts the FAKRA connector at the end of your factory antenna cable to an SMB plug that connects to your SXV100, SXV200, or SXV300 in-car tuner.
