My new Subaru! And some questions...

[Dabsos]

Hello! This summer I bought my first Subaru, a 2006 Legacy saloon. I completely love it, however there is one thing which annoys me. I don't know how to play music from my phone, put in a DAB radio, or make handsfree calls, since the radio and climate control is all one unit. Does anyone have a solution? I've realised it might have to be a custom job, but if anyone has any clue or anything it would be much appreciated!

I also was wanted to get an OBDII reader for the car since in the past I have hooked them up to apps on my phone (DashCommand, but maybe there's a preferred one..?) to monitor as many things as possible. Is there a good reader anyone could recommend, and a good app as well? 

Thanks very much if you read this, and looking forward to being a more active member here :)
