I have the LG G5 H820 with Android version 7.0. The radio system on 2017 Toyota Highlander Hybrid Limited will not display text messages from the cell phone.
I have called Toyota support, on the phone for over an hour, could not get messages to appear on car. Took the car to Toyota dealer, they did a firmware update, still car will not display text messages. Salesman said to check with cell phone carrier AT&T.
I have done the factory reset on the phone. No change - still text messages will not display on car.
A coworker has the Samsung S6 with Android 7.0, and an iPhone 6 with OS 10.3. Both of these phones work fine, the text messages will display on the car every time. Also, my brother has the Samsung Galaxy Note 4 with Android 6.0. The text messages will display fine on the car from his phone.
The problem seems to be in the LG G5. Trying to get it replaced under warranty, or swapped for a Samsung.
