Where to connect the ANT wire on an Android Headunit

The blue ANT wire may be included on your universal fit android head unit wiring loom, or it may be mentioned in the installation guide.

But do you need to connect the ANT wire for the headunit to boot up?

Where can the ANT wire be found on the android headunits?

Universal Fit

The universal fit android headunits, like any of our universal fit androids reviewed here have universal wiring connectors. Unlike the custom fit android headunits with their factory style connectors, ISO plugs are supplied with the universals for connecting to either an older vehicle directly or to a manufacturer specific adaptor cable. Some of the wires do not fit the adaptor.

Universal ISO system

The ISO system deployed by the universal fit android headunits gives a high degree of flexibility and reduces the need to cut and join wires. This is true from the main speaker and power connections, so these can be plug and play. This can also apply to the blue ANT wire but not always.

The ANT wire

ANT is short for ANTENNA. This still doesn’t help explain where it should be connected to when installing an android headunit. But to explain why it is called ANTENNA may help. The ANT wire, often the blue wire was originally designed to operate a powered retractable aerial. One that would retract into the vehicle body when the ignition was switched off. It would magically extend itself to full length when the radio is powered up.

ANT for an AMP?

An aftermarket vehicle amplifier needs to be powered up to make the loud sounds. But don’t use the ANT wire for this. ANT is not designed for this job and it won’t necessarily keep the amplifier switched on. If you want to use the ANT to switch on an external amplifier, think again and use the AMP wire instead.

What to connect the ANT wire to?

A powered antenna is obsolete now and has been replaced by flexible roof mounted aerials. But if you find yourself with an powered retractable aerial, ANT is what you need for your android headunit to operate it. Blue is usually the colour of ANT on a powered retractable aerial too.


If you don’t have a use for ANT wire on the android headunit, just insulate it and tuck it out of the way. Don’t cut it off and be aware that it must be insulated if not in use.
