This Item is off a 1998 328i, removed from a recent crash damaged car - I will say it was PROBABLY in good working condition, however we were unable to runtest this unit as it could not be powered (damage to battery area) . - unit comes with a 30 day functionality warranty, so if you are unsatisfied, you can return it.  Expect full functionality.  It MAY have a dead pixel, or a dead backlight bulb, however it should FUNCTION - regardless... if you are not satisfied with this unit, it has a 30 day warranty.
