There’s a new product on Amazon, currently on sale for $30 for Black Friday.
(Reg $50, now $30)
It plays through your car’s speakers via your smartphone’s Bluetooth connection. Voice control to stream from Audible, Amazon Music, Apple Music, Spotify, SiriusXM, and radio stations with TuneIn and iHeartRadio. Use your voice to play music, check the news, make calls, add to your to do-list, manage your calendar, and more.
I have not tested this device yet, but it looks interesting. (Not sure when the sale ends)
