Toyota and Xevo (Toyota's system software vendor for Entune 3.0) have found a problem that causes USB connection failures when the vehicle is connected to an iPhone that is powered by iOS 11.2 or higher. They are currently working with Apple to find and create a fix for this problem.
Currently, this problem affects 2018 Camry sedans and 2018 Sienna mini-vans that come equipped Entune 3.0 Audio and Entune 3.0 Audio Plus systems.
NOTE: Entune 3.0 Premium Audio systems are not affected because these come with built-in GPS navigation and are not compatible with Scout GPS Link.
Until Toyota announces a solution, Scout GPS Link cannot be used in MapStream mode (overhead moving map + 3D moving map during navigation w/ voice directions).
The TurnStream operating mode of Scout GPS Link should still work. TurnStream mode only needs a stable Bluetooth connection. All the basic features and functions of Scout GPS Link are still available, in a reduced content format. While you do not get an overhead moving map or 3D navigation, you will still be able to get turn-by-turn voice directions with turn arrows displayed on your head unit screen.
To learn more or to get updates about the Entune 3.0/iOS 11.2 USB connection problem, please call Toyota customer service and ask to speak with a Toyota Entune technical support agent.
Monday to Friday, 7:00 AM to 7:00 PM Central
Saturday, 7:00 AM to 4:30 PM Central
IMPORTANT: To keep your iPhone battery from being completely drained while you use TurnStream mode, we suggest that you connect your iPhone to a car charger. Even plugging a USB cable into the head unit merely to get power will also cause problems with Scout GPS Link.
