The XM SkyFi in our Sentra is starting to die. When it is turned on, it just shuts down randomly. I am not sure if it is a problem in the FM modulator or the SkyFi itself. Since I don't know what type of head unit I want to get, I just wanted to get something that would allow me to use my iPod in my car.
Since the factory head unit that I have has a cassette player, I wanted to try the SmartDeck, that I mentioned before. This iPod adapter allows you to use the cassette controls to control the iPod. By pressing fast forward on the head unit, it will either fast forward or skip tracks on the iPod.
It took me a while to get this to work. It might be because I haven't played a tape in years, but the tape kept ejecting. Once it started playing, I noticed that it sounded pretty muffled. Once I reversed the direction it sounded a lot better. (I am surprised that it only has the signal going to one side of the head.)
