Hi Dave.
1)EXP Autos Pro component support CSV/XML Import/Export , if you have XML files then more easy update.
But you'll have to change your
XML file in the format of the
EXP Autos Pro database.
2)You can Enable/Disable fields for each Category.
Please read and see video this
page >>>
If you want use others fields then you can :
1)hard way - add new fields in source code
2)easy way - change name for fields in languages files
3)Yes , you can switched off so that only minimal details are required to be entered in Configuartion component.
Again in this
page >>>
