Typically, a VDC output power supply is a simple AC-to-DC converter that has a power supply voltage of 110 or 220 VAC, and it converts this into a 3V, 5V, 9V, 12V, or 24 VDC. Overall, these VDC output power supplies are available in a variety of configurations, sizes, and output levels. As I am sure you are aware, DC flows at a consistent rateShort answer: yes, you can power both with a 12V 4A supply and NO, you can't use 24V 2A supply, it will fry everything most likely. Long answer: If one or both devices is sensitive to noise (eg an audio amplifier), powering two devices from the same supply could create noise that intereferes with normal operation (eg hum in speakers). If you find it then it's pretty safe to hook it up to a 5V input. Or B, connect the cigarette lighter plug to a 5V supply and see if it still outputs 3.5V, if it does then I'd see if the GPS works with it as well. Or C, get a Linear Voltage Regulator that converts 5V to 3.3V and burn off the excessive voltage×current in the form of heat.
to be able to derive V. ΔR. This can introduce additional challenges due to the limitations of standard measurement equipment. For example, a simple 4-digit multimeter used to measure V. OUT. and V. R. could produce rounding errors that affect the calculation of V. ΔR: if the multimeter rounds V. OUT = 3.0015 V up to 3.002 V and V. R = 2.9985
So the sensor has to be operated within a range of 4.5 V to 5.5 V. Undervolting at 3.3 V might actually not destroy the sensor but may (and will per joan's answer) significantly reduce the performance. It may fail at the most unforeseen moment or simply read nonsensical values. Simple put, it is not possible to use 3.3 V to operate this sensor.
