$170 · JVC KW-V31BT dvd/am/FM car stereo

Used, good working condition 6.1" touchscreen LCD with Bluetooth, HDMI, line in, microphone, and camera inputs. Has 3 sets of 4V preamp outputs. 50W x 4 channels means you can use this without an amplifier if needed. Has a USB port that can be used with a thumb drive for extra storage, or a smart phone. Also supports SiriusXM and steering wheel controls with adapters. My favorite feature is the volume knob. Too many devices are missing tactile control these days.
