To remove a function button from the Controller’s touch screen and iMap;

• Click on the Button Functions tab in the iMap software
• Click on the button you want to remove (it will be highlighted in blue)
• Right click on the empty blank space to the right or left of the function buttons (see image) 
• Choose Clear Current Button
• Your hardware controller’s touchscreen will also reflect the change.

(The photo below shows the iMap for the iCON V1-M, but the same method also applies to the P1-M, the P1-Nano and iMaps)
