Connection issues between my phone and my car?

I have a 2007 Mercedes-Benz c280, and it has the phone option with it. I have an iPhone 6s, and I was wondering how you are supposed to connect the two together to place/receive calls, etc. Is that even possible since iphones really weren't a big hit then, and Bluetooth really wasn't a thing? Thanks in advance

Added (1). UPDATE: It did NOT come with a cradle or whatever they're called.

IPhone data sharing?

My mom is getting an iPhone soon and I wanted to know how I can make it so my pictures and messages and stuff don't share to her phone. Which settings should i change and should I make my own separate Apple ID?

How can I clear my phone storage?

My phone storage has an internal memory capacity of 16 GB and right now it'd completely full. It never used to be this way until just a few months ago. I have only 9 apps installed (besides the ones already installed when getting phone) which is nothing compared to what people have on their iphones. That takes up 6.49GB. I took almost all of my photos off of my phone and put them on my laptop which leaves 5 photos on internal memory which takes up 1.03MB and some miscellaneous files I have take up 0B. So exactly how is all that taking up my whole storage? I presume that cookies and app cache are taking it up, but how do I delete the cookies on my phone? And not to mention some apps don't even have a button to clear cache so I would I do that in apps that don't have that selection. I'm just fed up with not being able to screenshot, watch musical.ly's, update my apps, sync my email or any of that. I just need help on how to clear things, because I don't understand how what I listed in taking up all my storage.

Candy Crush help with Level 1126? (iPhone)?

Not sure if this is a glitch, but I can't get the one fruit all the way down. Numerous times I've brought it down to the bottom of the center column, but no matter how many times I clear the two bottom bombs out of the way, the fruit won't fall through, and instead 2 new bombs fall into place. I tried using stripes, bomb-stripe combos to knock them out, but the fruit still won't go. Any advice?
