Hi Piocdx
I am trying to upgrade from the standard radio, cassett, air con unit to a nav screen unit. Mine is a1999 GS300 the, unit is from another 1999 GS300. If i connect the plugs from the old unit into the new i get nothing except the control backlights.
I am sure there must be some other form of connection, wire, configuration i need to make, can you help?
I dont nessicarily need the Navigation to work just everything else.
Many Thanks Steve
