This $3 USB adapter fixed all of my Apple CarPlay connection problems

I bought a new Jeep last year and was obviously adamant that it had CarPlay. It was also the first car I owned with a touch screen for CarPlay, which is a nice change of pace. But in the first couple of weeks of driving, I was increasingly frustrated: even though I was using a wired USB connection, my CarPlay kept disconnecting. Sporadically, and frequently.

I tried different phones. I tried using an official Apple Lightning cable — USB-A and USB-C, as my car has both — as well as various styles and lengths of third-party cables. Nothing worked. And then, I found an inexplicable fix: using a simple USB-A to USB-C adapter, which is just $9 for a three-pack .

I had a few of these USB adapters already because I find a need for them occasionally as I mostly use USB-C cables nowadays. I even carry one in my backpack in case I need to plug in to an old charger or outlet on the road. And I’m so glad I got frustrated to the point of trying them because it fixed my CarPlay connection problem immediately. A simple Lightning to USB-C cable, attached to this adapter and into the USB-A port on the car, works flawlessly.

I can’t tell you why this works (I won’t pretend to be an electrical engineer), and I’m honestly quite confused because you’d normally expect an adapter like this to make the connection less stable. But there’s something about the translation between USB-A and USB-C using the adapter that helps the car understand it, without fail. And though I don’t know why it works, I’ve been driving my car carefree for several months without a single CarPlay dropout.

If you for some reason have a car that only has USB-C and still have issues, you could always try using an adapter that works in the reverse direction, from USB-C to USB-A — they’re about the same price.

If you’re having issues with your CarPlay or Android Auto connection, these adapters are worth a shot. It worked in my Jeep, so I would expect the best results with any Chrysler, Jeep, Dodge, or RAM model. And if you have a different brand of car, it’s an inexpensive solution worth trying anyway. And if it doesn’t work for your CarPlay issues, they’re still useful to have for other uses. It’s a win-win.

Study: Motorists using Apple CarPlay are more distracted than drunk drivers
2021 Hyundai Elantra

Driving while impaired is often vilified as the most dangerous thing to do on four wheels, but a recent study suggests using infotainment software like Android Auto and Apple CarPlay reduces a driver's reaction time more than booze or pot. United Kingdom-based road safety advocate group IAM RoadSmart wants the government to take action.

The group pointed out the average driver's reaction time is about a second; that means when the car in front slams on its brakes, it's going to take a full second for the person following it to do the same. That figure increases by 12% when someone takes the wheel after reaching the legal alcohol limit, and by 21% when a person drives after smoking or eating cannabis. Using Android Auto and Apple CarPlay increased the reaction time by 53% and 57%, respectively.

Many criticized BMW's unusual decision to charge its customers an annual subscription fee to use Apple CarPlay. While some feared this would become the norm across the industry, it's turning out to be a short-lived exception to the rule. Digital Trends has learned that the German company is making the feature free across its range of models starting immediately.

"BMW is always looking to satisfy our customers’ needs, and this policy change is intended to provide them with a better ownership experience," a company spokesperson told Digital Trends.

How tech is making trucks comfier, smoother, and better for everyday drivers
2020 Ram 1500 EcoDiesel

Trucks are more expensive than they’ve ever been, but that hasn’t done a thing to slow Americans’ growing demand for more and better pickups. Trucks are also more advanced, safer, and more comfortable than they’ve ever been, thanks in large part to widespread use of new technologies and better construction materials.

After spending a week with two greats from Ford, the Ranger and the Raptor, as well as significant time with several others, I’m convinced of the upside. New trucks are every bit as accommodating as passenger cars, and in many cases they match top luxury brands in delivering a tech-forward, comfortable experience. Other than the challenges of navigating a large vehicle around places that aren’t really designed for them (cough, cough, New England), there is very little daylight between a pickup truck driving experience and that of the cushiest cars.
