Yep, the "L" Rev. does have Artist, Album, Track. It's pretty good. One word of warning tho from the Polish site you get the full kit inc. foam mount/guard. From the ebay site (of the polish company) you DON'T get the foam mount/guard. I had to pay the installer £10 for it.

Is the facia the same for the Columbus and rns 315 and does the 315 use a separate mic

Yes and yes
