So, there are 3 ways to determine which iDrive system you have: 1. By the year of production - this doesn’t guarantee that you will be able to determine your iDrive version with 100% accuracy, because in some countries the production month can be different. 2. By the interface - The majority of iDrive systems have specific interfaces, so it’s also worth checking out the look of the menu in comparison with other head units to identify the iDrive version. 3. From BimmerTech - just type your VIN and we will send you your car’s specifications including the head unit, i-Level (software version), etc.
