We purchased 2 2018 Camry SE
We purchased 2 2018 Camry SE Hybrids a week ago and yes Scout GPS is horrible, if it even works. The fact that you have to have the app open & plugged into the USB to show the map is rediculous. My wife's iPhone 7 in her car will connect to show the map about 50% of the time. My iPhone 6 has NEVER been able to connect in my car to show maps.
Plus side, I spoke with my friend at Toyota and he said they are going to be releasing Apple Car Play through an OTA update to all vehicles with Entune 3.0. He estimated it will be released by either the end of 2017 or early 2018. I did not ask about Android, but would assume it will be released as well.
