OTIS or OTIX- this is the overhead console that shows mileage,distance to empty etc.There are two types- OTIS is used in all LH car lines ,and OTIX is the new one on the 300M luxury package with the menu button that allows you to customize certain settings( this one will only fully work on 2001 and up cars, it will partially work on 98 -00 cars ) Yes you can add this to any LH car The computer has all the info built in.Some of the things may not work if you try to add the console with the MENU button as it needs the high line body controller and a few extra sensors. The wires are not there from the center console to the left fuse panel area were it plugs in, but if you can find a donor unit the mounting bracket is waiting under every headliner. All you have to do is cut the hole and run the plug down to were the current plug is that gives power to the overhead map lights. Actually very easy. The hard part is finding the donor console and harness.
