anyone?

Evening all, I have been searching the internet for an answer to my question but with no luck! I've got a 3 series e91 on a 56 plate and want to be able to control my iPod from the radio. I don't have £300 to spend so the dension option is out the window, xcarlink don't do one for the e90 so there out. Any other suggestions can try? For info I have got the bmw professional head unit and a cd changer in the boot. Thanks in advance for any help. Chris
