Bimmer Retrofit Apple Car Play Adapter for NBT Installation
----Description from Website----
The most complete Apple CarPlay wireless integration for your NBT iDrive is finally here!
Our CarPlay NBT adapter allows integration of the CarPlay system in to existing NBT system in your vehicle. Adapter connects to existing NBT iDrive system and uses it to display CarPlay mode while communicating with your Apple device wirelessly (Bluetooth and WiFi).
Once connected with your Apple device you can enjoy a variety of iOS apps on the BMW NBT display. This is not a true screen mirroring solution, but Apple CarPlay is as close as it gets to screen mirroring - it lets you use Apple Maps for navigation and traffic, access iTunes and send text messages! More functions will be added over time by Apple/BMW.
If your vehicle is already equipped with NBT iDrive you should be able to install this adapter
There is no need to perform any coding or configuration of your NBT system to work with CarPlay adapter. The only configuration required is Pairing of your Apple device via BT with CarPlay adapter.
If your vehicle is not equipped with NBT iDrive, no worries! We can provide you with everything that you will need to install NBT or even NBT EVO retrofit (has built in native CarPlay) in your car. For more information on the NBT EVO retrofit in your specific car, please see this link and email us with the VIN of your car.
