I have a problem with my car aux cable?

Whenever I plug in my iPhone to my aux cable into my car the sound is all fuzzy and only plays through certain speakers. And the phone has to be held in a certain position for the sound to work so I have to hold it up and keep it still which I obviously can't do when driving. Anyone else had this problem? Is it the phone or the car, I want it sorted - thanks

Where should I get iPhone 6s? Rogers? Bell? Telus? Apple?

I've been researching their deals online but they are so similar. I'm currently with Rogers and my contract has ended already, so if all deals are similar, I should just stay with Rogers, right?

Another way I'm thinking is buy it in full from Apple then choose a different service. Maybe Wind for its unlimited data?

Please advice.

Can you back up one icloud account on more than one device?

My iphone 6 broke yesterday and we can't get it looked at until the 18th (todays the 13th) so i decided to use my old phone (iphone 5). I couldnt remember the passcode to that one and had to restore it to factory settings. If i back up my icloud account onto my iphone 5 could i still back it up onto my 6 if it has to get wiped too?

Finishing a Three contract and starting a EE?

My 3 contract ends in April, and its expensive to pay so i want to finish it and not renew the contract, just end it and get a new one with EE, I'm getting a iPhone 6s and I'm wondering if it will cost more? I looked at the plans and all of them cost £41, which is a little bit less than what I'm paying for but I'm okay with it, my friend says that its going to cost even more, why?
