Only some 2005 models of the MINI Cooper feature Bluetooth capabilities. The 2005 model year was the first in which Mini Coopers saw Bluetooth integration for audio streaming and hands-free calling—but it’s unclear whether every model sports this feature, and the ones that do have it in a fairly limited capacity.

In 2005 Mini Coopers equipped with Bluetooth, only three devices may be paired to the vehicle anytime. That means if you want to connect a fourth phone to your car, you’ll have to manually delete one of the previously paired devices.

The MINI brand didn’t standardize Bluetooth connectivity in its Coopers until 2014 (nearly a decade after the feature was first introduced!). If your Mini Cooper came with the owner’s manual still intact, chances are you’ll be able to uncover whether or not you drive a Bluetooth-compatible car by checking there.

But if you conclude that your trusty Cooper lacks hands-free capabilities, you still have options—like adding a Bluetooth adapter to your vehicle. While at it, don’t forget to add the right used car coverage to your insurance policy!
