What does this blue plug on the radio connect to?

Does anyone happen to know what this blue plug connects to on this 2020 Toyota radio. Thinking of upgrading a radio but unsure what that plug is for

 

I thought it was for the gps, or sat radio antenna.

 

The gps is the white square plug on opposite side on bottom of radio and black square is the XM antenna. I was wondering if the blue plug could be for phone wireless charger. It’s the only thing I can think of but can’t find anything for sure.

 

This sounds like a good question for @caribe makaira

 

Is that radio a JBL headunit?

That connection appears to be used, somehow.



Could be for the hotspot transmitter.

The following threads might help.

Since everyone likes to guess...
Maybe it's this...

 

Thanks for the replies. It looks as though it is used for a DCM/hotspot transmitter. The pic of radio in first post was a non JBL but it had the real navigation not scout gps. What I’m actually trying to upgrade is my 18 Camry XSE. It’s supposed to be the top of line Camry but mine came with bottom of line radio. No cd and no xm. The back of my radio looks like thisAnd the radio I found to replace it with has everything but Navigation, it has the scout gps and looks like thisThe reason I asked on here is cause I don’t know of a Camryworld and the Camry radios with the full navigation system look the exact same in the back as Tacoma’s look. If I find a radio priced reasonably on Fleabay I may try to upgrade without the DCM. I have XM and GPS antennas to make rest of radio work
