The Audio Player Connected/Disconnected has been flashing constantly for about 10 minutes or longer, then suddenly stops. This has been happening for about a week or two now. Anyone know what is causing this before I take it to the dealer and have them run a diagnosis?.

 

Sounds like a bluetooth issue. Have you tried re-pairing the phone? Tried a different device as a bluetooth audio source?

 

Is our phone plugged into the USB, or just connected via Bluetooth?

 

No I haven't but will try it, thanks.

 

Bluetooth always.

 

Mine did the same thing on my 2018. Fixed it by unpairing from my phone and re-pairing. You could also try to reset Network Settings on your iPhone if that is what you use.

 

Go to www.lexusdrivers.com and look under the Resources tab for Multi-Media updates.
What year is your GS350? I found that only the 2016 MY GS350 has an available update
at this time. This is NOT a navigation update, it is to update various drivers such as Bluetooth.
If yours is a 2016 you just download to a USB thumb drive and then use the drive to update
your car.
