Street names sent from CarPlay to the car's HUD get truncated down to 5 characters in iOS 18

They aren’t even planning on fixing it unless more people actually complain directly to them. Apple engineers do not see the shortened street names as a problem at all. They do not monitor these boards. So until enough people call Apple at 1-800-275-2273 to complain, this will never get on their radar to be fixed through an update. I talked to their senior case advisor, and she told me the only way we will see a change is if people to call them directly instead of complaining on these boards.

PRO TIP: You will probably first get someone who wants to trouble shoot the problem by having you reset or restart your phone or car. DONT! We know no fix exists right now, so all this will do is disconnect your call or make you have deal with resetting your preferences again. Just skip to the part where you demonstrate the problem for them, and take a screen grab of the jacked up street names. Hopefully enough people will do this so we can get back to the full names before OIS 18.
