I too have a Pioneer the AVH-3300NEX single din unit. Flip out 7" screen. With DVD/CD, carplay, android auto, blue tooth, USB, Aux, backup camera (need additional camera and cable) SIRIUS capable (cable and subscription required). I upgraded Business unit with this. So here is the list of what I had installed. All cost in US dollars.
AVH-330NEX - aprox $500 (yes over paid but chip shortage) so very hard to find unit.
AXXESS Steering Wheel Control Interface- $59
Metra *AWG AMP Kit-$79
Kicker AMP CX400w class D Digital Amp with low pass cross over $145
I agree with previous post which love the unit and functions. Sounds fantastic but wish it fit flusher with the dash.
