So I've decided on ditching the Pioneer double din and doing something else...
8" Acer Iconia tablet (android, can use usb thumb drive, and all kinds of cool apps and stuff)
NVX 7 band EQ (has two RCA inputs, will use 3.5mm to rca y cable to run from tablet to EQ. EQ also has front, rear, and subwoofer output so Ill have outputs for all of the amplifier channels my system has. Also has front 3.5 AUX in on the front, and a dedicated volume knob since the tablets volume control is on the side.)
Ill make sure I take step by step pics for those who want to see. Wish me luck!
