Samsung Galaxy S5 / Amundsen - lack of track details

Hi.

I have an Octy Elegance (03) which is just under a month old.  I love it.

It has the Amundsen head unit (and I treated myself to the Canton sound upgrade).

I have a Samsung Galaxy S5 and have no issues connecting the phone to the unit and playing media or making phone calls.

However, If i use any other music player on my phone apart from the proprietory samsung music player, no details of the audio tracks/albums are displayed.

I dont think its a Skoda issue........ but has anyone else had this problem and are there any fixes?

Also..... why do only some of the contact pics in my phone book appear on the screen. 

Thanks
