Do i need a specific cable for my pioneer car stereo?

Just got a pioneer AVH-X4500BT and my appradio app isn't working, I have a jail broken iphone 4s and the "display out" tweak didn't do anything either. I'm using the stock iphone usb cable to plug into the deck, but either I need the specific brand cable or I just don't know what i'm doing. Any advice?

Using an iPhone 5 in Europe (wi-fi only)?

I'm going to be traveling to Europe for almost 3 weeks and am bringing my phone with me. It is an iPhone 5, Verizon 4g lte. I only want to use it for Wi-Fi when I'm over there.

If I put it on airplane mode with Wi-Fi turned on will this be all I need to avoid having Verizon charge me for anything, even if nothing should be coming through?

I was planning to call Verizon directly but would truly love to avoid a conversation where they try to sell me plans worth hundreds of dollars for my trip. Any information is appreciated!

Can't take another picture on my iPhone?

I have 82 pictures, 0 videos, 163 songs, but 29 apps. My iPhone says it doesn't have enough memory to take another picture. This is getting ridiculous because I feel like I'm deleting pictures and apps and texts every week to save memory. Is this normal?

Added (1). The ones that consume the most memory are Instagram and my Music. Also, most of my apps are photo editing apps so does this have anything to do with it?

One of my usb ports isn't working?

So, basically, I was trying to use iTunes to put songs on my iPhone using my desktop. I have a wireless mouse which constantly uses one of the ports. I have to use the only other one to plug in my devices, and it won't work. I have another little usb man thingy that has a lot of different ports that you can plug in and then plug the whole thing into the computer to use 5-6 at a time, but that doesn't work for both the mouse and the iPhone in either of the ports. So right now it's either I use the mouse or I plug the phone in to iTunes, both of which are pointless because I need both to put the music on. How do I fix the port and what's wrong with it and is there any way to use the single port with both?
