Most older cars don’t have built-in Bluetooth, unfortunately, so you can’t wirelessly stream audio or answer hands-free calls. This little portable Bluetooth receiver changes that. It plugs into your car’s 3.5mm aux input and allows you to stream music through the car’s speaker system. It’ll also allow you to stream music to your analog bookshelf speakers. Or it’ll allow you to use your wireless Bluetooth headphones with your Nintendo Switch. It’s a simple upgrade to bring you (and your car) into the streaming age.
