The main differences between the 187A and 187B lie in memory and mobile phone functionality. The specific differences and the features of the 187B are as follows: Specific differences: Compared to the 187B, the 187A is an older model. The 187A requires a memory replacement to enable CarPlay, while the 187B has larger memory and supports CarPlay without the need for flashing. The 187B supports Apple and Baidu mobile phone connectivity for functions like navigation, which the 187A does not support. Specific features of the 187B: Supports CMMB digital TV, true-color HD digital screen, intelligent digital operation platform, integrated development based on ARM architecture Windows CE intelligent operating system, ensuring more stable system operation, faster speed, and more powerful functionality; ultra-strong electronic anti-shock; supports rearview camera, solving the problem of reversing for car owners.
After using the 187a and 187b car head units for a while, I noticed the most obvious difference lies in hardware performance. The 187b processes much faster, with no lag when launching navigation or music apps, while the 187a sometimes stutters a bit. Additionally, the 187b has larger memory, allowing it to run multiple functions simultaneously, such as Bluetooth calls and music playback without interference. In terms of features, the 187b supports Apple CarPlay and Android Auto, enabling direct phone mirroring to the large screen for more convenient navigation and message alerts; the 187a only supports basic MirrorLink, which is less flexible. Battery management has also improved, with the 187b being more power-efficient. Overall, the 187b is more suitable for those who prioritize speed and new features. If you frequently drive for business trips, this upgrade is worth it.
