NX450h steering wheel controls

[BonzoSPB]

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?

Try looking in the manual, it should tell you which buttons do what

Manual no use I'm afraid. After a long period of testing it looks like there's no way of doing this using the wheel buttons which appears rather strange.

Does the 450 have the right/left buttons on the bottom of the right hand steering wheel controls?  I don't use a USB stick but that scrolls through the tracks when I play music through an attached phone.

Ah - I see what was happening now. When I initially used the right\left buttons on the right of the wheel the system always moved to the first artist on the USB stick and didn't scroll through the tracks on the current album but, it appears that I was doing this before the system had completed reading in the necessary data off the USB stick. If I wait a couple of minutes and try again the buttons successfully scroll through the album tracks. Thanks for your help!
