I just installed the Universal G13 2 din. But, it is not powering on. I have a multimeter and tested B+ and ground on the wiring harness while car is off & it reads 12v. I turn car on & test ground, B+ and ACC all read 12v, but screen shows no signs of life. I also removed the red fuse in the back which looks good, reinstalled fuse & turned car back on, but no signs of life on the dasaita unit. I also tried the reset button, but no change. what should I try next?
