<font color='#000000'>What is different in RF Modulaotors.
My CD changer came with an RF Mod. which allows the changer to play thru an unused FM station. My car radio has no input plugs.
My XM radio came with an RF Mod. to also allow the signal into an unused FM station.
Can the RF Mod from my CD changer be used on my XM.
Is there an inexpensive RF Modulator that I can purchase to use on my XM system?</font>
