I have a 2000 S80 with an HU-801 radio. This morning, the car started as usual but there was no power to the radio. I changed all of the radio fuses. However, the radio will still not turn on. There were no clues that there were any problems with the radio at all. Any clues?

Do you have vida or other capable scanner? If this car is similar to 01v70xc, starting the car with disconnected radio will result in srs light(unless my memory failing me, but i believe it is the case). I have no suggestions outside of checking powers and grounds to the radio unit first. The connector pins are small, thus it wpuld be best to invest in automotive back probe(can be also used as front probe) connector kit(i believe i paid $35 for a kit from amazon with banana connectors and extra multimeter wires) and with proper electric diagram, check if you have proper powers/grounds with key in "accesory" position. Alternatively, junk yard/ebay and get yourself another radio for $50 and play swaptronics.
