I have the same problem in my UK 63 plate ST. I've tried changing some settings in forscan but still haven't found a solution.
Someone on a FB group said he had the same issue and this is how he fixed his, it didn't fix mine but it might work for you.
Using forscan, go to "PID information and settings", "In Car Entertainment", and select "06", then press the tick.
Then go to "Touchscreen", and select "07", then press the tick.
Finally write.
Obviously make a back up of your cars file first before changing anything.
Also do you have the D1BT Bluetooth module in your car? You'll know if you do if your car displays the artist and song when playing music though bluetooth.
Hope this helps and we find a solution soon.
