Change car charger to iPhone car charger?

Is it possible to change a regular car phone charger to a car charger for iPhone? I sometimes use a plug in thing for a regular phone and put my iPhone USB cord in it to charge it, it there something I could do with the car charger? And I'm not going to buy one. So don't say buy one.

Doesn't always work, because there's so much power needed for the phone to charge.

  • How to charge my iPhone in my car without an actual car charger? I'm going on a long road trip.

  • Is there a car jack to plug into my iPhone to listen to music in the car? So I have been wanting to listen to music through my iPhone in the car for awhile now since burning CDs is not something I specialize in. Is there a car jack for this so that I can play music over the stereo system? I have a 2004 Volvo XC90 if it helps. -Thanks!
  • If I buy a new stereo for my car with a USB port can it work in any car? My stereo in my 1998 transport just died. This surprisingly excited me. I just got a new IPhone and I'm constantly installing new music. I'm wondering if I can buy a radio with a USB port and put it in my 98 transport even though my car didn't come with a USB port in the radio. Is this at all possible?
  • How to hook up an iPhone to car speakers (No car stereo)? I'm converting a 1955 Triumph TR3 and would like to install speakers to play music from my iPhone. The car currently has no stereo, speakers, or wiring for anything of the sort. I don't want to install a radio because I wouldn't listen to the radio at all. What is the easiest way to hook up an iPhone to the speakers I will install? If the easiest way is to use a radio as an amplifier, so be it. Any links for additional help would be appreciated.
