Many times the low/no sound issue for any of the sources (CD/FM/AM) is the result of bad capacitors in the output stage of the head unit itself. If you are skilled with a soldering iron and can read the values of the capacitors and replace them without burning the PCB, you should be able to replace them no problem.

If this is beyond your skill set then going with an aftermarket head unit and amplifier is the most popular option. Choice is yours. We do have some guides here in the audio/electrical section that may be of use to you.
