i need some help finding a head unit. its hard to find what i want just by searching goodle images, and going to manufacturers websites. so heres what im looking for...
1) atleast one usp port in front
2) a turn volume control knob, ( i want to be able to make quick volume adjustments )
3) gps
4) touchscreen
5) double din
6) aux port in front
7) doesnt disassemble. ( i want it locked into my truck. i dont want the face to come off )

Its going into my 1997 chevy k1500 Z71
if you know anything that closely matches these, please let me know. im not looking for the cheapest units, because i do want quality. but im also not looking for the most expensive
