I'm a proud new owner of a NX450h and have so far mastered most of the technical side of things but have not being able to work out the following:
I have a USB stick which is full of music and plays fine in the NX450h.
I can change the 'source' using the centre button of the left hand arrow set to change the between DAB, FM, Phone and USB. If on FM, DAB or USB I can see a list of stations or tracks on the album I'm playing in the centre console but there doesn't appear to be a way of scrolling up\down the stations\tracks using any of the steering wheel controls. If I press up\down the system simply changes the source and appears to act like the centre button.
Is there a way of scrolling through radio stations or USB media tracks using the steering wheel controls?
