The Plus continues to pair with your smartphone to get online, and can use either Bluetooth or an aux cable to pipe music to your car's audio system. An OLED screen provides basic navigation details so you don't miss a turn.

Not surprisingly, the addition of the camera raises the price. The Speak Plus will sell for $230 when it ships in mid-February ($200 if you pre-order by February 10th), or well over the $150 for the original Speak. But it might make more sense. Many people are content with mounting their phone and using its built-in assistant, and there's not much point to Speak if you have a vehicle with Apple CarPlay or Android Auto. However, dash cams are a different story -- this gives you some useful safety and insurance features in addition to keeping your eyes on the road while you drive to an unfamiliar destination.
