USB UPgrade

Hey everyone,

I just installed an aftermarket dual USB port from Amazon (

$18 QC3.0 +PD3.0 USB Power Socket, 60W Output, Type C & Quick Charge 3.0 Car Charger USB Adapter for Smart Phone PDA iPad iPhone Android GPS Use for Toyota (Type A)

https://www.amazon.com/dp/B0B8NS1281?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1), to replace the OEM USB/AUX jack next to the cigarette lighter in my 5th gen 4Runner. The new unit connects directly to the 12V lighter socket for power, but it completely omits the original plug that was connected to the OEM USB/AUX module.

My question is:
Where does that original plug come from, and what exactly is it for?
Why is it being bypassed in favor of just tapping into the 12V outlet?

Is this plug connected to the head unit for data (e.g. CarPlay or audio input), and if so, does skipping it mean I’ve lost functionality?

Appreciate any insight or wiring diagrams if someone has gone down this road. Thanks in advance!

 

The original USB port is generally data only and barely charges.

 

Data from phone? My phone connects (I think) thru wirelessly or bluetooth but not have the CarPlay functionality ('17 TRD PRO) so I can continue with this set-up without loosing any functionality? thank you again for your quick feedback.

 

Originally intended for USB music and Entune connectivity since Toyota refused to add Carplay/Android Auto because they're 20 years behind with their features.

You will be fine without it if you don't use it.

 

I use the OEM USB Port for music mainly or updating the head unit software.
Since my T4R is a 21, if I plug my iphone into it, after removing the usb drive, I can run Apple CarPlay. Otherwise I just have my phone connected via Bluetooth.

 

Yes I wish we had the newer headhunt to be able to connect to CarPlay!
