I bought this for Kevin for his birthday in 2019 and he absolutely loves it. His car doesn’t have bluetooth connectivity, an aux line, or even a tape deck, so he wasn’t able to use his phone with his car speakers.

This nifty gadget gives him the ability to broadcast his phone wirelessly over bluetooth, and even allows him to answer the phone! It’s super easy to set up, and it’ll work in any car with a DC port (cigarette lighter port).
