I recently contacted Toyota UK and this was the reply I got:
Thank you for your email regarding Mirror Link, hopefully the following information will help clarify a few points.
Mirrorlink is an Android compatible feature that allows compatible handsets to display approved apps from your phone on your cars infotainment system.
Mirrorlink is owned by a US Company and has no affiliation with Toyota.
Mirrorlink has 2 versions currently (1.0 and 1.1), and a 3rd (1.2) is being developed and as such we have no timings or details of what it will contain or do. No version is compatible with the others. For instance if your car was version 1.0 and your phone was 1.1, they would not work together.
Apple do not currently support Mirrorlink.
The Toyota Touch 2 with Go system on software versions 4.1.1, 4.2.0, 4.2.1, 4.3.0, 4.4.1 and 4.5.0 are Mirrorlink 1.0 compatible.
The Toyota Touch 2 with Go system on software versions 6 or later as well as the X-Nav and X-Toyota are Mirrorlink 1.1 compatible.
The only phone that was compatible with the Mirrorlink 1.0 system was the Samsung Galaxy S3.
Most modern Android (post 2015) phones running Android software 6 or later are compatible with Mirrorlink 1.1.
To use Mirrorlink with your car you need to have the phone connected via bluetooth with the car, and then connected via USB.
If your phone is Mirrorlink 1.0 you will need to download the Samsung DriveLink App from the App Store. If your phone is Mirrorlink 1.1 compatible you can enable Mirrorlink within the settings menu of the phone.
Once Mirrorlink is enabled you will be able to access the compatible Apps on your phone via the infotainment screen. To view compatible phones and applications please visit:
as very few apps are compatible, and if no compatible app is installed on your phone all you will see is a blank screen.
Please note that Mirrorlink also stops you using your phone whilst the phone is connected with the car.
Mirrorlink will only let you use certain Navigation Apps, a limited selection of Music apps, and allow you to see text messages, bluetooth music and receive phone cars on your car. Most, if not all, of these functions are already available on your cars infotainment system.
I hope this information has been useful and thank you for contacting Toyota.
