2005 ashtray unit
 

How do you remove the ashtry cigarette lighter unit form the dash.

Take off the center bezel and you will be able to access the ashtray.

From what?

Dashboard Ashtray
 

To access the entire Dash Ashtray you have to remove the Center Bezel that surrounds the radio and climate control. Now before taking that Bezel off you have to un click the Center Console lid that surrounds your Shifter. The You tube link will point out the connection points. When these pieces are off you can work with the ashtray better and it helps letting you disconnect the ashtray from the Dashboard. This is the way I replaced mine.
