X30 Nuances

Have just aquired an X30 to go with my X10,X12,and X14.

Sound quality seems to be a cut above the baby models, however i think ive got one with issues.

1. Keeps switching itself on, have to turn off with the back switch to stop it after its powered down.  Any known work around for this.?.

2. Have set the display as per my X14 to not display artwork when playing, however it seems to ignore that and displays artwork in the left of the screen, i prefer to have just text.

Have gone through all the settings but ignores them.

3. Volume controls on the remote do not control the volume, having to control from my Bose Amp set up. Have tried both Analog out and coaxial.

Obviously just niggles but would have thought it would function as per it baby brethern

Thanks  Bri
