Iv looked through all the various threads about aux and none help. Iv got a 2011 evo and when i was at the garage i looked at 2 different evos. One car had the windows usb and the other had both the usb and 3.5mm AUX input. Now the car iv got has just the usb and i was wondering how hard is it and if possible is it to install and aux input as connecting my phone and having to control the ipod through the steering wheel gets annoying anyone done this or any help?

Now i did take out my radio and took a few pictures so you can see which one i have.

Thanks
