well i recently updated my firmware software becuase my z1 would freeze when it is hot but now i can't watch movies just by flashing my headlights what cna i do to fix the problem?

on the side note im sorry for the noob question i did search but hardly found anything on helping me with this problem

You will need to do the 2 wire bypass for full functionality while driving. Check the sticky posts at the top of the forum for directions.
