With the Connects2 Bluetooth Music Streaming Interface, you can use Bluetooth to stream music to your car radio from any smartphone, tablet, or other mobile device. You can use this device with any smartphone model that has bluetooth, but it is essential for models like the iPhone 7, 8, and X and later that do not have a headphone jack output. When you connect via Bluetooth (A2DP), your dashboard is free of unsightly wires. These Bluetooth interfaces are a great way to play music in your car and are very simple to install!
