Apple CarPlay is a great program for car iOS devices. For older MMI 2G, there aren’t much choices since it’s an old technology. There’s a program by third party who claims to mimic the Apple CarPlay from Apple, but it doesn’t work as well as Apple original software.
If the App can access the iMessage data and work like the original Apple CarPlay, it may worth the money, but without the iMessage hand free feature, it defeats the purpose. I’m glad that they have 7 days trial.
Apple CarPlay exists in 2017 eGolf and it works wonder with the touch screen, but since Audi MMI 2G doesn’t have touch screen but we can use the Analog TV tuner to mirror the iOS screen to MMI screen and use our iOS device as touch screen.
