Alpine's navigation system is a great upgrade for many vehicles, providing clear voice and images, a larger selection of music, and a customizable split screen. However, it can be difficult to use for those with older vehicles, as it can be difficult to navigate folders and the color on maps can be washed out. Additionally, it can be slow to connect to a regular radio and can be slow to recognize CDs and DVDs. Despite these issues, the Alpine system is a great choice for those looking for a reliable and stylish navigation system.
