Bought the unit, it is not powering on. Customer service have been out due to national China day holiday for 4 days. I called them today, they are out due to weekend. Bunch of idiots who don't read or understand English. I keep telling them that I have 12V going to the unit and still not powering up, all fuses are good. They want to send me a wiring harness. I am tired of messing with these people. Save yourself the headache and by something in US so it can be returned in case. DON'T WASTE YOU MONEY.
