Easy To Replace A Lexus Headunit With A Pioneer?

[DRFRAME]

Does anyone know if I can replace the headunit in a 1997 ES300 with a new Pioneer headunit that will still control the Lexus CD changer in the glovebox?

I have a Japanese equivalent of a 1997 ES300, a 1997 Windom. The stereo's headunit includes TV, Navigation etc... , it has 7 speakers and the usual Lexus 6 disc changer in the glovebox. The screen on the headunit has died and I need to replace the headunit. The navigation screen is too costly to replace considering there is no navigation software for it for my country, New Zealand.

I know the stereo system was made by Pioneer and Nakamichi and hope I could easily change it over, but want to make sure before I spend the money on the Pioneer one (probably a DEH-P2650 or DEH-P4650MP, both have changer controls).

Nothing seems to be a compatible unit

Maybe you can get a used OEM replacement from EBAY?
