koasonnavi.com is the official e-commerce site for the Koason brand. Koason is a manufacturer with over 10 years of R&D and production experience, specializing in custom upgraded center console display solutions for older BMW, Mercedes-Benz, and Audi vehicles. Its core value proposition is replacing the original screen with a higher-definition touchscreen while retaining all of the vehicle's factory functions, and adding practical new features like wireless CarPlay and Android system expansion.
All products on the site are vehicle-specific custom units, covering multiple model years and series of BMW, and also offering compatible options for Mercedes-Benz and Audi. Products support retaining all original factory functions including the factory iDrive system, let users switch between the original system and Android/Linux with one tap, support wireless CarPlay/Android Auto, and come in multiple screen sizes: 8.8-inch, 10.25-inch, and 12.3-inch. Processors range from Qualcomm Snapdragon 8953 to 680, storage options go from 4+64GB up to 8+256GB. Additional features include split-screen display, DSP sound tuning, 4G cellular connectivity, and support for external accessories like reverse cameras and dashcams.
Pricing is tiered based on configuration, with single units ranging from $249 to $579 USD. Optional accessories are priced separately, and free shipping is offered to customers in Europe, the US, and Australia.
Pros: After years of refinement, this brand's products have excellent compatibility, and can almost perfectly retain all original factory functions. The screen display quality is a massive upgrade over the small factory screens in older vehicles, and the value for money is far higher than official upgrade packages from 4S dealerships. Users with basic DIY skills can follow installation tutorials on YouTube to install the unit themselves, no complicated programming is required.
Cons: Products lack comprehensive printed installation instructions, the software UI interaction is not very polished, and there are some minor issues like static on the original Bluetooth connection and lack of support for a few languages. There is still room for overall improvement.
This site is perfect for owners of older BMW, Mercedes-Benz, and Audi vehicles who want to upgrade their center console screen and add wireless CarPlay functionality. The site is currently directly accessible from China, supports direct ordering, but customers are responsible for covering international shipping and customs clearance fees themselves.
