I have audio for navigation but none for the radio or media, when I click on selection I can navigate to the folders on both sd and hdd but when I click a song it doesn't start to play. 

 

Update, I think I may have a dodgy connection in the bluetooth loom when placing the stereo in, how does everyone get around the space issue at the rear? I disconnected the loom and reconnected and its working now.

I cut away some of the radio cradle on the side, very easy to fit the radio with the looms behind now

Thanks Eddie I'll get the dremel out

It also helps removing the top box and moving the wiring about from above.

That was a lot easier, I removed quite a large amount of plastic from the side. Also slit my hand open on the cut plastic but I have voice control working now. Likely never use it but my completionist issues compel me to sort it anyway!
