I got this same problem. some part of your wiring is bad. Its a real pain to figure out what part some of it is wired to the clock some is wired to the heating plug and some of it is just out there.

putting in aftermarket radio and need color codes for 1998 Hyundai Sonata GL L4-2.oL
Could be broke, or might just be a Hyundai radio. Check antenna, and cable from antenna to radio.
you could go to radio shack and get an installation kit for 96' elantra and it is self explanatory.
It does not have that option in the stock radio
The radio unit on a Hyundai Elantra is held in place by a mounting bracket found behind the center console. First remove the center console then remove the screws on the mounting bracket. The radio will be able to slide forward. Once pulled out remove the wire harness that plugs into the radio.
mine did same, 95 elantra. it was fuse for radio in fuse box. hope that helps.
I've not done it yet but I found this web page with instructions. http://egt.gwebworks.com/garage2.shtml

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
No one seems to have a good answer for the LOADING problem. I removed the Batt. cables and the LOADING went away for a couple of days but came back. I've had it with Hyundai, they just say buy a new radio because they don't know what to do.
I had problem on my 2001 Elantra with power for radio, inside light and trunk light. I found the fuse in the fuse compartment on dashboard on the left side from the steering wheel. To acces it you need to pull out the coin holder. Inside you will see the fuses and diagram with tags. Radio was in the second row on the right if I remember correct. Good luck.
