A much better option than those cheap, wireless FM transmitters.

My 2nd Sirius aftermarket radio apparently has a wimpy fm signal transmitter, since I very often lose the signal (not the Sirius signal; the FM station I'm trying to use for the Sirius signal).

Sound quality is far superior to any wireless solution - even your hacked non-compliant RF transmitter.

Sound was dramatically better than using a cassette adapter or the crappy FM transmitter on the Onyx SiriusXM receiver.

For this reason, newer units (newer than approx 06-07) have a very weak transmitter; which makes the volume of your Satellite Radio way lower than anything else you would listen to on your stereo.

Not 100% perfect as I do get dropped stations here and there, but 99% better than a tape player or over-the-air radio.

But totally worth it sound is just as good as if you had a built in AUX cord from the factory
