USB outlet iPhone flickers on/off upon insertion

Yep mine does the same thing. We kept on thinking it was the cable. Now I know it’s happening to someone else.

 

yep, what iOS are you running? I'm running 12 beta, and I've noticed it doing it. Hadn't seen it before.

 

NO.

Because that likely is happening because the two systems are "talking" to each other and the car is "logging" any files it finds on the phone......like music files.

If the blinking light is the ONLY indication you have of that going on, count yourself lucky.
My wife's phone causes a message to pop up 4 or 5 times complaining that it can't find any "media files" before it finally gives up.

 

I’m also running 12 beta but I’ve had this issue since somewhere in the 11s.

 

I'm pretty sure this has nothing to do with the operating system our phones are running.

The car pulses the charging circuit 3 times when an iPhone is plugged in. It charges extremely slow, if at all. Then the headunit will crash if I take a long drive. It's a known issue and Toyota seems content with the trash infotainment they've been putting in their cars for years. (Entune)

Carplay would seemingly fix all of this, but Toyota's stubbornness prevents that from happening.

 

+1 for this issue. I changed cables and it helped.
