We also like that the Drive GPS units can double as a display for an optional wireless backup camera or rear-seat baby cam.
If you can’t find our main pick or just want more convenience features, you can get the pricier Garmin Drive Smart 51 LMT-S.
Voice controls let you easily input a destination without having to type a name or address on the screen.
And, more important, we didn’t find the screen information to be quite as informative or as easy to access as Garmin’s, nor did we find the voice directions as driver-friendly.
While the Tom Tom model typically told us to turn at a specific street name, for example, the Garmin units’ voice directions referenced easily identifiable landmarks such as a traffic light, a stop sign, or even “the red building.” Even so, the Go 50 S works fine as a basic navigator for everyday use.
You can still buy our previous top pick, the Garmin Drive 50LMT, until stock runs out.
It’s essentially the same as the Drive 51 but without Bluetooth and Trip Advisor ratings.
For example, it will display a forward-collision warning if you’re driving too close to a vehicle in front, and a lane-departure alert if you begin to drift out of your lane.
It can also detect a crash and automatically send a text and map link to a preselected contact.
Our new runner-up and upgrade picks are the Garmin Drive Smart 51 LMT-S and the Garmin Drive Assist 51 LMT-S, respectively, both of which are updated versions of our previous picks.
All of our previous Garmin picks are still available at discounted prices while supplies last.
After spending more than 70 hours researching the latest car GPS models and testing the top contenders over 1,200 miles of rural, suburban, and urban orienteering, we recommend the new Garmin Drive 51 LMT-S as the best in-car navigation device for most people.
