What do you do if the stereo does not work in a 2004 Hyundai XG350?

I am not sure about this one. I can only assume when you say,"stereo", you are refering to the sound quality of 360 degrees of sound. If thid id your question, then you may have a loose speaker wire connection on the back of the radio. This connecting can only be accessed by physically removing the radio from the alcove in which it sits and thoroughly examining the speaker wire connections. Another possibility is that your antenna may have come unplugged. The antenna is located IN the rear windshield above the defroster veins. I am unsure as to where it connects to as I have only had my XG350L for only a little over 5 months. There are other possibilities. There are two fuse boxes in this vehicle. There is a fuse box in the engine compartment next to the air filter and another fuse box that is very hard to reach under the dashboard on the driver's side. Look for a fuse marked, "Radio" and gently remove it with the pinchers supplied in the engine compartment's fuse box. Do you see a thin piece of metal through the plastic casing that connects the two prongs electrically? This piece of metal should be intact. If it is broken or severed, you will need to replace the fuse. Here is a nice little trick on how to test if a fuse is blow: Fully remove the fuse from the fuse box. Get a 6-volt Lantern battery and a small 12-volt bulb. (An automotive bulb will do. Use a Sylvania 1156 Reverse Lamp bulb.) Place the bulb's metal base on the negative (-) spring of the battery. Place ONE prong of the fuse on the positive (+) spring of the battery. touch the other contact of the fuse to the bottom metal tip of the buld while making sure the bulb's metal base is still contacting the (-) spring and one fuse prong is still contacting the (+) spring. If the bulb lights up dimly, the fuse is GOOD. If the bulb does not light at all, the fuse is BAD. If you have tried everything and still cannot get the radio to work, you may have to get a new radio! Sorry for all the details!
