Apple Makes Meaningful Change to CarPlay

Despite carmakers sinking untold amounts of R&D trying (and mostly failing) to convince us otherwise, many drivers prefer a measure of smartphone mirroring to whatever iConnectStarDriveLink car brands foist upon their wares. In that vein, Apple has made a small but notable change to CarPlay in its latest iOS update.


With screens in our vehicles rapidly growing to jumbotron sizes, third parties like Cupertino are able to make tweaks to take advantage of the digital real estate. The new (beta) version of iOS 18.4 now permits a trio of icon rows when connected to certain infotainment systems – namely ones which have a screen size rivalling that of the television we had in the living room forty years ago.

It isn’t clear what the screen size cut-off for the presentation of three icon rows but an appropriately new iPhone running the beta of iOS 18.4 on a top-trim Civic with its fresh 9.0-inch touchscreen will find the system capable of displaying a tri-row of Day-Glo apps. The same is also reported for machines like the new Toyota Tundra equipped with the huge 14.0-inch screen. However, we could two rows of icons on an 8.4-inch Uconnect in a Stellantis product using an iPhone 15 Pro with iOS 18.4 this morning, so that size screen might be the floor.


These examples are screens oriented in the popular landscape position, of course. There have been numerous cars with portrait-style tablets which have been able to display more than two rows of icons for some time now. However, those models don't always have as many icons on their x-axis.

Why does any of this matter? Because convenience, of course. CarPlay (and Android Auto) provide a dose of familiarity to users, having been immersed in their environments for a spell. It arguably reduces distraction if a driver can interact with an interface they immediately recognize instead of relearning a ton of commands each time they get behind the wheel. Being able to simply interact with apps like Waze is a boon to unfussy driving. Of course, your gearhead weirdo authors around here would rather the simplicity of controls from a ‘90s econobox but we all know that’s not happening again any time soon.

  • MaintenanceCosts The Truth About Isuzu Troopers!
  • Jalop1991 MC's silence in this thread is absolutely deafening.
  • MaintenanceCosts Spent some time last summer with a slightly older Expedition Max with about 100k miles on the clock, borrowed from a friend for a Colorado mountain trip.It worked pretty well on the trip we used it for. The EcoBoost in this fairly high state of tune has a freight train feeling and just keeps pulling even way up at 12k ft. There is unending space inside; at one point we had six adults, two children, and several people's worth of luggage inside, with room left over. It was comfortable to ride in and well-equipped.But it is huge. My wife refused to drive it because she couldn't get comfortable with the size. I used to be a professional bus driver and it reminded me quite a bit of driving a bus. It was longer than quite a few parking spots. Fortunately, the trip didn't involve anything more urban than Denver suburbs, so the size didn't cause any real problems, but it reminded me that I don't really want such a behemoth as a daily driver.
  • Jalop1991 It seems to me this opens GM to start substituting parts and making changes without telling anyone, AND without breaking any agreements with Allison. Or does no one remember Ignitionswitchgate?At the core of the problem is a part in the vehicle's ignition switch that is 1.6 millimeters less "springy" than it should be. Because this part produces weaker tension, ignition keys in the cars may turn off the engine if shaken just the right way...2001: GM detects the defect during pre-production testing of the Saturn Ion.2003: A service technician closes an inquiry into a stalling Saturn Ion after changing the key ring and noticing the problem was fixed.2004: GM recognizes the defect again as the Chevrolet Cobalt replaces the Cavalier.fast forward through the denials, driver deaths, and government bailouts2012: GM identifies four crashes and four corresponding fatalities (all involving 2004 Saturn Ions) along with six other injuries from four other crashes attributable to the defect.Sept. 4, 2012: GM reports August 2012 sales were up 10 percent from the previous year, with Chevrolet passenger car sales up 25 percent.June 2013: A deposition by a Cobalt program engineer says the company made a "business decision not to fix this problem," raising questions of whether GM consciously decided to launch the Cobalt despite knowing of a defect.Dec. 9, 2013: Treasury Secretary Jacob Lew announces the government had sold the last of what was previously a 60 percent stake in GM, ending the bailout. The bailout had cost taxpayers $10 billion on a $49.5 billion investment.End of 2013: GM determines that the faulty ignition switch is to blame for at least 31 crashes and 13 deaths.It took over 10 years for GM to admit fault.And all because an engineer decided to trim a pin by tenths of a millimeter, without testing and without getting anyone else's approval.Fast forward to 2026, and the Allison name is no longer affiliated with the transmissions. You do the math.
  • Normie I'd hate to have to actually use that awkwardly mounted spare tire in a roadside fix scenario. Bumper jack? Tote around a 50 lb. floor jack? That's a high ridin' buggy!
