04 GXL 120 - Radio Antenna Wires to rear of Radio - Appears there are 2 - why

[KRH Lurker Find all posts View Profile Close KRH]

I had to pull my centre radio panel to access the rear harness wires
The person who installed and aftermarket touch screen unit for Prado from Elinz.com.au a few years ago forgot to re-connect the clock/outside temp plug to the factory readout screen.
Anyway i noticed a second antenna cable with a smaller size connector on the end compared to the standard size radio antenna plug.
I pulled my Factory radio out of storage and checked the rear and could only find 1 x standard size antenna port and not a 2nd smaller one
I google searched and found a rear view of a Factory radio with a 2nd Antenna input port called - Ant (sub) which is also a same smaller size

It appears this 2nd antenna jack from the wiring loom is not being used in my case
Can somneone clarify its use
My aftermarket head unit has just the same standard size antenna port but not a 2nd smaller port for a 2nd antenna plug

My Elinz Head Unit has all sorts of modern day options and the rear panel has mutliple plug options (besides the wiring loom plug receival ports)

Iam going to leave this 2nd antenna cable/jack hanging loose as nowehere to plug it into anything
Hope someone can solve the mystery of the 2nd cable
Thanks

That would be for the GPS antenna.

Hi All,

I bought one in the US saying for Toyota car vehicles to retain USB connection but unfortunately not working . Got pictures to show but I have to work it out how to upload it .
