Sort tracks by track number??

[dj_vts]

Hi everyone my name is Bill and i am from Greece. I own a pioneer avh-x8700BT (i think the us model is nex-4100?) and i have an issue with it. When i search for music on my 500gb HDD with the "Tag" option from the left in order to search for artists,albums etc. and select an album, the tracks within the album are sorted alphabetically and not by track number, even though i have all my music correct with ID3 tags, including track number. Is this happening to everyone? Is there a setting maybe that changes it?

 

Also, is there a "Search" function that pops up a keyboard so we can search manually for artists,albums,files etc.? This would be very useful. I read the manual but didn't find something.

 

I sent an email to Pioneer Europe but never got a response back..

 

Thank you, and sorry for my English!
