Hi there, thanks for reaching out.
The MagEZ Case 2 for iPhone 13 series belongs to MagEZ 2.0, so it can’t work with yout CD slot charger, which is MagEZ 1.0. You can upgrade your car charger to the MagEZ Car Mount Pro.
Thanks for your great support for PITAKA.
Please feel free to contact us if you have futher questions.
