If you want to change out the Head Unit and want full control of everything but the CD changer, then the Amp will need to be replaced as well and be wired to the new Head Unit bypassing the Fiber Network. With replacing the Head Unit you will be able to find a system that won't need the phone to stream from your favorite source.
But if all of this is more than you want to do, SUNNYT's recommendation of getting a cable that plugs into your cellphones headphone jack and then plugs into the AUX jack on the left side of the glove box is the simple answer.
Best way I can describe it is like driving a C63 AMG in “Sport +” mode 24/7. For me it was a pure performance mod as I didn’t like the “floating boat” feeling on the highway. Handling has improved a lot, but on 20” wheels the “comfort” is gone. Couldn’t imagine this on 22” unless your roads are smooth as butter. You feel all the bumps and changes in road surface, but it sits like a sports car on the highway and turns a lot better. Definitely a sporty mod that eliminates a lot of body roll.
I would advise buying adjustable rear camber arms, like mentioned in my signature, with the mod as you will be entering a strong negative camber. If you want to have 100% tread coverage, it is needed. Your toe will be ok, but camber is too far to be corrected with factory equipment.
My my car is aligned like a BMW M3 with aggressive rear camber, which makes it a champion in turning.
It’s all in what you want out of your car.
If you just want to lower it to look cool but want the comfort, then no. Do not do it.
If you want performance and aggressive handling, then yes by all means get the performance suspension.
