1DIN car radios with Bluetooth are the most common type of car radio with a universal size designed for most older vehicles. The standard 1DIN size is approximately 178 × 50 mm, which corresponds to the classic frameless opening in the dashboard of most cars. These car radios can be easily installed using an installation frame and mounting brackets, often without the need to modify the interior. With integrated Bluetooth, you can play music wirelessly, stream songs from your phone, and use hands-free calling for safer driving. 1DIN car stereos with Bluetooth are the ideal choice for drivers looking for a combination of compact size, modern connectivity, and easy installation.
