It might be because the car's hidden features haven't been 'unlocked'. You can visit a 4S dealership to resolve this. Below are detailed specifications of the 2014 525 model: 1. Engine: The 2014 525 Luxury is manufactured by BMW Brilliance, classified as a mid-to-large-sized car. It features a 2.0TL4 engine with turbocharged intake, delivering a maximum horsepower of 184ps and a peak torque of 290nm. The transmission is an 8-speed automatic with manual shift mode, and the body style is a 4-door, 5-seat sedan. 2. Dimensions: The 2014 525 Luxury measures 5087mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3108mm. Its top speed is 230 km/h, and it uses the B48B20C engine model with an inline cylinder arrangement.
I've been driving my 2014 525 for almost ten years, and indeed, the Bluetooth setup in this car only supports phone calls, not directly connecting to a phone for music playback. At that time, BMW kept the music streaming function in the optional Professional Navigation package to control costs, so the standard version's Bluetooth module lacks the A2DP protocol. You can check your vehicle order or VIN code to confirm if that package was installed. If not, don’t worry—I often help friends upgrade by adding a Combox module or a third-party Bluetooth receiver plugged into the AUX port, which costs around 300-500 RMB and adds new features without affecting the original car system. It’s also important to remind technicians during regular maintenance to check connections to avoid aging issues. In short, don’t blame the carmaker for being frugal—technology wasn’t as universally standard back then, and aftermarket solutions are now very mature.
For those who have been driving this type of car for a long time, it's quite common for the 2014 525 model to only support Bluetooth calls but not music playback. This is because the basic version of BMW didn't come standard with an audio streaming module unless you opted for the professional package when ordering the car. The root of this issue lies in the compatibility of the head unit system, as the older iDrive didn't integrate those features. I recommend first checking if there are any additional options to activate in the glove compartment or control panel. If not, don't force it to avoid damaging the circuitry. Nowadays, upgrading isn't difficult. A local repair shop can install a small adapter box to connect to the AUX or USB port for wireless music playback. I've used one, and it's quite stable with sound quality comparable to the original setup while being more cost-effective. For older cars, wiring may have poor contact over time, so it's advisable to regularly check the fuses as a precaution.
