Show two apps at once on Android 5.1.1?

[King Mustard]

I have a Pumpkin 13-RQ0278E-UK car head unit (specifications below).

It has Android 5.1.1 installed.

Ideally, I'd like a music player on the left side of the screen and Google Maps on the right side.

Is this possible?

Specifications

Rockchip SoC
Intel Atom "SoFIA" 3G-R CPU
Android Open Source Project (AOSP)
2 GB DDR3 RAM
1024×600 resolution
