Hello Fordguy210,
We just want to make sure we're completely clear on your question, so we can help. To clarify, are you wanting to know if you can use CarPlay with your iPhone when using a MagSafe charger? If so, please check out this link, which outlines the available options to connect iPhone to CarPlay, and may be helpful: Connect iPhone to CarPlay
Connect using USB
Connect iPhone to your vehicle’s USB port using an Apple-approved Lightning to USB cable.
The USB port may be labeled with the CarPlay logo or an image of a smartphone.
Connect wirelessly
1. On a vehicle that supports wireless CarPlay, do one of the following (see your owner’s guide for detailed instructions):
* Press and hold the voice command button on your steering wheel.
* Make sure your vehicle is in wireless or Bluetooth pairing mode.
2. On your iPhone, go to Settings
> General > CarPlay > Available Cars.
3. Choose your vehicle.
Note: Some vehicles that support wireless CarPlay allow you to pair simply by plugging iPhone into your vehicle’s USB port using a Lightning to USB cable. If supported, after you start CarPlay using USB, you’re asked if you want to pair wireless CarPlay for future use. If you agree, the next time you go for a drive, iPhone connects wirelessly to CarPlay automatically.
Thanks!
