Is my current system compatible with Nest? My thermostat is a Honeywell TH8320U1008. There is a jumper from R to RC.

As the wire in your O/B-W connector is orange: you probably have a heat pump, so I've used those wire labels not the conventional wires. Looking at those wires, it should be compatible with all models of Nest Thermostat. Nest Thermostats don't use jumper wires, so don't connect that during setup.
