will this work with a 2008 scion and an iPhone 4?

I have a 2008 Scion xB and an iPhone 4. I can get the iPhone to play and the car will read out the song title and artist, but it will not charge my phone. I want to buy this but not if it still won't charge! I also have a JVC portable speaker system and an alarm clock that I would love to use. I may just buy it and try it...
