Ok, I am not a car person, and I am not a stereo person so I know I am completely out of my depth here so please keep that in mind when trying to answer my questions. And I also know that this topic has been hashed out a million times, but the more I read the more confused I got. So I am looking for a nice streamlined answer, if there is such a thing. I have a 2006 G6 with a factory non-monsoon 6 CD changer, which works fine but has no aux in port. I have an old portable Sirius radio which also works fine, but the FM transmitter cords are shot, and I hate the bad quality of the sound when you try to listen to it over an empty FM station. I also have an iPod, and run into the same problem with crappy sound from the FM transmitters. I don't want something that charges the iPod because my husband has the iPhone 5 which uses the new style charger, and my phone and iPod use the old type so I just want to plug it into the headphone jack. I've looked into after-market stereos with the Sirius already in them (so I can just eliminate my old portable radio) and with aux ports for my iPod. Here is a link to the after-market stereo one of my friends recommended: http://www.crutchfield.com/p_130X7500S/Pioneer-DEH-X7500S.html#details-tab But, I got scared off by what people have said with the message center (DIC?) not working. I'm pretty sure I can hook the Sirius radio I have now to an aux port so would a FM modulator be a better option? The friend who recommended the after-market stereo will be installing whatever I end up getting, and he is good at this kind of stuff. What I am really trying to figure out is what is my best option to get all of these different radios to work and sound good. Thanks in advance for your help!
