I have had 2 different installers look at the system, all ascratching there head.

 

- I cannot get the navigation to go into night mode. (illumination wire is hooked up correctly, getting the correct voltage, but reading not connected in the hardware connections status check)

 

- When I turn the unit off, my amps stay on and just keep running. (It was originally hooked up to the antenna wire, which turned off all of the amps when I turned that off - but now that its hooked up correctly, I cannot turn off the amps!)

 

- System "hisses" terribly. (All wiring has been completely redone, re-routed, etc. - by process of elimination, 2 installers think its the HU???)
