How to solve the problem of no Bluetooth in a 2015 Q3?

First, download your favorite songs on a music app. Transfer the music files to the car USB drive, preferably placing them in the root directory to avoid the vehicle system failing to scan the files. After downloading, insert it into the vehicle's built-in USB port. The car's system will then automatically scan the music files on the USB drive.

My 2015 Audi Q3 didn't come with Bluetooth, which is pretty common. A simple solution: get a Bluetooth FM transmitter that plugs into the cigarette lighter. I picked one up for around 100 yuan on Taobao—pair it with your phone and broadcast to the car stereo, sound quality is decent for music and calls. The downside is occasional signal interference, especially in urban areas with static. For long-term use, I recommend upgrading to a third-party multimedia head unit with Bluetooth, costing around 1,000–2,000 yuan but a permanent fix. Remember, don't DIY the wiring during installation; find a reliable technician to ensure safety and a clean look. Hands-free calling is super convenient while driving, avoiding the distraction of reaching for your phone.
