Hi. Looks like you have the same model as me. I didn't think there was an SD card reader except the one which is for the Navigation only. I had an SD reader in my old car (Skoda) but had to move it onto a USB stick for the Mazda. Works fine from that.
I meant the micro SD card in the phone....
My old car had SD as well.
I was hoping to not use a USB so I could have 2 phones connected.
I can play from the phone by controlling it from there.
It would be nicer if I could use the nav system as the controller
