PLEASE NOTE:
If your Mazda BT-50 originally had the OEM GPS system installed, you need to
plug in a different radio antenna. Instead of using the radio antenna that normally
plugs into the back of the OEM CD housing
(the connector that you originally unplugged), you must use the radio antenna that
was originally plugged into the the back of the OEM GPS Screen (it is the black
connector).
1. Before re-mounting the OEM
CD housing we suggest posi-
tioning the power amplifier
box just behind it.
