well i just finished installing my nav 2 tv mod but i noticed in all the forums that you are all useing a switch to switch to change from nav to tv mode i decieded to put in a relay so that when i power up the dvd player it automaticly switches very ez and less wires and switches to have

 

That's great and all, but without a switch you need to power off your dvd player each time you need to check your navigation.

 

Thats true... Didnt think about that...
