IPhone Aux Problems in the car?

When I plug my iPhone into my aux in my car, I listen to music but I also want to make and receive calls through the radio. When I do, I'm able to her the other person easily, but I can't talk to them because they barely hear me. When I put it on speaker, it comes out the phone and not the radio.
What can I do without buying another radio or bluetooth?

Why is my macbook not recognising my iPhone?

This is a problem that's only started recently but when i plug my phone into my macbook most times it doesn't do anything. Sometimes it will charge but most times it doesn't and even if it charges it doesn't come up in iTunes.

It charges fine when I plug it into the wall so I'm assuming it's not the cable. My mac's still under warranty if it is that but my phone isn't.

Any suggestions of how to sort it? Oh and my software/itunes is all up to date as i've just checked.

How to unlock an iPhone 3GS that has been reset to factory settings?

My friend gave me her old iPhone 3GS. I reset it to the factory settings and was planning on taking it in to Tmobile to have it hooked up. My problem is i can't get in to any settings or anything now since it was restored. The only thing on the screen is the unlock slider and once you do that it just says emergency call and the little i symbol with the IMEI number. Can I unlock it from here somehow so I can use it?

How to download music from my iPhone to iTunes?

I just got a new macbook air and all of my music from my previous computer is on my iPhone. I asked the people at the Apple store how to do it but they said that since I have music on my phone that I didn't purchase, the songs will get deleted when i sync my phone to the computer. I don't want to lose all of my music so how can I transfer all of my phones music to my computer without losing all of it?
