iPhone Insanity

[martyman.geo]

Hi all,  I have a 2015 DJ SXT with the 8.4 (non-Nav). Since I have had this DJ, there have been multiple mechanical issues covered under warranty as well as the entertainment system going crazy.

The radio has the DVD option, rear camera ( Installed and had the dealer activate it), and active Sirius.

After the first year, the radio suddenly had a mind of its own with the volume sliding up to max while the car is in motion as well as the inputs cycling through am, FM, DVD, Sirius, and locking into the aux.  (there was nothing connected in the RCA jacks).  The warranty covered the replacement of the radio and the out of control 8.4 came to a grinding halt.   A month later, the overhead entertainment screen stopped functioning (dealer diagnosed it as not communicating with the radio). The screen was replaced under the warranty as well.  The curious thing the dealer had mentioned or inquiried about was if I plugged my iPhone in the USB port in the armrest storage.   He had mentioned it could cause the electrical malfunction on the radio.  

 

This may sound a bit silly, but until the service person had mentioned it, I did not realize there was a port in there.  I thought it was only a light in there due to the rubber plug covering the socket. Fast forward to Dec 2018, My wife plugged in her iPhone into the outlet because I had my phone plugged into the external cell charger. (combo charger and holder plugged in the power point ).

 

This is where the insanity piece comes in... Immediately after she connected in the USB port, the screen began blinking then getting fully scrambled, then the radio rebooted.  I reached over and unplugged her phone from the USB port.  The radio screen blacked out then looked like it rebooted.  All functions went back to normal.  After that, I was reluctant to even connect my phone via Bluetooth to the radio.  Since I use hands-free, I still connected via Bluetooth.

Fast forward again to Jan 2019, I went to the dealer for an oil change and asked if they could check it out.  Because the 36,000 warranty was over in Jun 2018, they wanted to charge to diagnose the issue.  This is the same dealer that replace the radio and overhead screen. They suggested not to connect the iPhone to the USB port.  The other item I noticed was the audio lag when connected to Bluetooth with movies/music videos on the iPhone (for the back seat passengers to watch Netflix on longer drives)  the audio is about 3 seconds behind the video.

 

Is this normal?  we both have iPhone 6 Plus's. Does anyone have any recommendations or thoughts?
