CarPlay installation

Hi everyone,
I’m looking to install Apple CarPlay in my car and was wondering if anyone could help me out.
Where’s the best place to get CarPlay installed?
Should I go with an official dealer or a third-party shop?
How much does installation usually cost?
Any brands or head units you’d recommend or avoid?
For context, my car is a [car make/model/year].
I’d appreciate any recommendations, experiences, or rough price estimates. Thanks!
