Denton, TX

Great way to add iPod/Sirius functionality

January 9, 2012

I purchased this item to avoid taking my eyes off the road when using my iPhone for music playback through the AUX analog input which was shared with my Sirius portable. The ISGM571 meets my needs and provides an excellent user interface. I can now leave my iPhone and my Sirius tuner connected and have eliminated the myriad wires I had running around the car. Installation was simple as advertised (the hardest part was figuring out how to remove the radio bezel). Information not appears on the radio display and controls are also through the factory radio. The only downside is iPod/iPhone music interface. I have my entire music library included, and it takes some time to run through the artist or album list to locate the disired selection. Once selected though, the sound is excellent.
