Got this hint on another board and its answers all your questions!
Goto www.hmaservice.com (Hyundai webtech 2000) Set the Model Year and engine drop-downs on the top of the page and then click Search on the far right. Try entering the search kewords "dashboard", "interior" and/or "radio" (leave all items as the default values)
["dashboard" worked for my 2004 Elantra, and "radio" for my 2000 Elantra]
You should get a "Removal" or "Instruction" document that you can click on. This contains all the details of removing the dash assembly and radio.
Enjoy!
I went to the website and this is what you get although the pics didn't seem to work here. I ran into some snags where there was not nearly enough info and so I added a bit between steps three and four.

REMOVAL AND INSTALLATION
AUDIO
1.
Disconnect the battery negative terminal.
2.
Remove the shift lever boot and the rheostat assembly using a (-) driver.
3.
Remove the center facia panel's 2 mounting screws. (2EA)
At this point it is going to tell you to pull off the facia panel. You will want to
get down and unscrew the heater control cable down near the gas pedal.
There are two screws holding it in place. One is holding the cable casing
and the other is holding a white piece that swivels attached to the cable.
Once these are free the facia piece should come free. If you do not do this you'll only have about a half inch of play and will probably break a clip yanking on stuff. You can do the rest without removing
all of the wire assemblies attached to the facia panel it is a little in the way
but manageable.

You match the yellow with the yellow the red with the red and so on...
there's no such thing as a Hyundai ''lantra'', its elantra If it's the same as Elantra try modifiedlife.com. They got free wiring diagrams for many makes and models. Sorry. There is a Lantra. It was released in Australia by Hyundai during the late 90s. There is a sedan and a sports wagon.
Try this site. I got the one for my 1998 Elantra and well as the alarm diagram. It was free and basically: click on Car Stereo Wiring Diagrams near the upper left of the page, click on Hyundai where all the makes are and then look to the right for the car you want. www.modifiedlife.com
Your car should have came with a card that has the code. Look in the manual and in and on the glove compartment for the code. If it is not there you will have to have the serial number from the stereo and call the dealer for the code.

Remove the retaining cover from your factory stereo. Remove the factory stereo retaining bolts. Slide the factory stereo out. Remove the wiring harness and the antenna cable from the back of the factory stereo.
Call Crutchfield. They have the installation kit, diagrams and instructions.
If you have the factory installed Monsoon stero, you cannot. Must must but a new stereo that has an audio jack.
