User level: Level 1 (4 points)I recently upgraded from an iPhone 14 Plus to an iPhone 18 Pro. I already have an Apple Lightning to USB cable (1 m) that I used with my iPhone 14 Plus.
Can I use my existing Lightning-to-USB cable with Apple’s USB-C to Lightning Adapter to connect my iPhone 18 Pro to:
Will this combination support data transfer and wired CarPlay reliably, or should I purchase a new USB-C cable instead?

Yes, you can use that combination for both.
Apple’s USB-C to Lightning Adapter supports data transfer, so your existing Lightning-to-USB cable should work with a PC. The adapter is limited to USB 2 speeds, up to 480 Mbps.
It also works with wired CarPlay in most vehicles. Apple does note that some combinations of the adapter, cable, and car stereo can cause connection problems.
So I’d try what you already have first. If CarPlay is unreliable, I’d use a direct USB-A to USB-C data cable instead. That removes the extra adapter and is the simpler connection.
