To my knowledge it has never had the "screen repair" done and is a totally original good working unit. - however I think at some point (last 5 years probably) it was a replacement genuine saab unit.  It was fully functional - I plugged this into my friends 1999 Saab 9-3, and we ran through all the screens, and noted no faults.

I will give a 20 day satisfaction guarantee with this unit.  Very cheap compared with rebuilt or new!
