Ford explorer 2000, car stereo and speakers?

Added (1). I have no idea about cars and I want to ask for a new stereo and speakers for Christmas. I don't know what to look for, I don't know if it will even fit. I'm so confused. I know I want built in bluetooth and gps in the stereo. But that's all I know. Someone please help me.

Any radio will fit your car can hold a single or double din radio which if you're wanting gps I recommend double din touchscreen well I would recommend it period your speaker sizes are 6x8 in the front and back which 5x7 is the same size and there's more to choose from in that size I would recommend a pioneer or Kenwood stereo and Polk audio door speakers or Memphis or alpine but Polk would be my choice download an app called Metra if you have a smartphone and it allows you to put in your vehicle information and tells you what parts you need and speaker size and by parts I mean dash kit and wiring harness for the radio
