It is different between click the power button and switch the acc off first.Click the power button just keep the unit in stand by mode and the unit will constantly waste power.However ,after you switch the acc off ,there is little circuit wasted by the unit.
About your issue, you can first check whether you click the following option on.You need to switch it on.
And if it is on, did your unit fast boot when you switch acc on ? if not,you need to exchange the yellow wire and red wire from the power cable back of the unit.
More query,please first tell me your order number in amazon or buyer id in ebay,Pumpkin or AliExpress so that we can confirm more information about your unit and provide you positive solutions.
Please also tell us your car model if you don't mind.Thanks.Statistics: Posted by Jammy — Fri May 18, 2018 3:20 am
