Bluetooth, Bluetooth, Echo, Echo
 We have a 2017 Highlander, Limited AWD with the JBL premium sound system.  If you have a choice, DO NOT get the JBL system.  The Bluetooth system is terrible and EVERY phone call has a terrible ECHO making it unbearable to use.  We end up picking up the phone and not using hands free which is a big safety issue and illegal in some states.  I have had it to the dealer 4 times for this, and their final response to me this week was that it was a JBL issue and until JBL fixes it for them, there is nothing they can do.  "Please be patient with us and we will let you know when it is resolved".
