Welcome to the forums, Justin! I'm sure you will find most of us very passionate about our vehicles. Your parents are probably having a blast with their new 300c and would also benefit from joining this forum like you!

Regarding the audio system, studying your owner's manual is a good start. You can also go to the Car Audio/Alarms/Navigational Forum and do a "search" for specific information. If you don't find what you are seeking, then feel free to post a new thread in that forum. There are lots of 'experts' in all the various forums. Believe me, I have learned so much and am very thankful to all those who have responded or from just reading other posts/answers. Good luck in your quest!
