Currently I have a Note 3 with Samsung authentic (purchased locally from Best Buy store) MHL adapter, I have plugged in the power to its micro USB connection, short 1M HDMI cable to the back of HU.  When I go to Contacts, or anything, trying to scroll any pages, would flip to a black screen, sometimes it may come back in few seconds.  If I go to the GPS, it doesn't work at all just showing with a black screen.

 

Do I have a bad connection?  I know there's a kit from Pioneer, do I need to purchase that?

 

Much appreciate your help.
