The performance of this car is obviously good, but the lock down started within 5 days from the date of my purchasing of this car, I have not used it much, for sharing my experience, But my concern is that I have purchased a S9 variant, Your website and all other leading sites are saying that S9 variant has a Navigation system inbuilt, But I am not being able to find this in my Car, even my dealer also saying that It does not comes with S9 variant, I would like to ask the writer of this article, that from where you have got this information that S9 has a Navigation system in it, If the reviewer has seen any of the S9 with a Navigation system, please let me know that, Please let me know that how to install the navigation system in S9 variant, even after purchasing the vehicle, Regards, Sanjit Saha, Siliguri, West Bengal.
