For those that did not know, yes, you can hook up a Stem player to a car. This can be done in 2 ways: Aux input or Bluetooth. Aux input: Aux input requires an auxiliary cord with a 3.5mm jack and a female-to-male headphone extension cable. The cable connects the Stem Player to the back of your car’s stereo system. Keep in mind that if you’re using aux input, there may be interference when the volume is too high on either end. Bluetooth: If your stereo system has Bluetooth capabilities, I recommend using that as it will be much easier and faster than aux input. First, make sure your Stem Player is paired with your device. Next, turn on Bluetooth on both devices. Once connected, use any music app on your car’s stereo system (Pandora, Spotify) to wirelessly play music from your device. The playlist will now come through your speakers.
