i have a CarPC that im not using anymore and thinking about parting out.

OPUS 150w that runs/works great
Liliput 7" touchscreen that works great
and one of the typical usb gps receivers that worked fine the last i used it

had the stuff for like a year and a half but only used it for maybe like 6 months. i always ran the touchscreen off the OPUS's regulated DC-DC power instead of off the shitty cig lighter port which burns out screens. let me know if you're interested in either of them
