Eliminate static with the FMDA25 hardwired FM direct adapter. The adapter installs behind your car stereo between the FM antenna and the car stereo, virtually eliminating static. If you live in an urban area with high FM-station density, interference from neighboring or weak FM stations can often creep in and create static. The FMDA25 relay device makes a direct, wired connection from your SIRIUS radio to your vehicle's stereo, shielding the system from intrusion by over-the-air FM stations. This part is fully compatible with all new receivers featuring PowerConnect and many older SIRIUS & XM Receivers that have a FM out plug on the back or side of the car cradle.
