I have a 2000 Gs-400 with hard drive navegation. Is it possible to replace the hard drive unit with a dvd one without replacing the screen ? I mean, so I can still , without to much complications, use everything else , radio , temp, etc with the same connections and screen ? I really will like to know, to start looking for one. Thanks....

 

More than likely there will be different plugs and configurations, so probably not possible.
