ios - Relationship between CarPlay and External Accessory and Wireless Accessory Configuration -


for current project supposed develop iap2 on usb connectivity head unit (mfi certified) developed 3rd party.

the requirement continuously uses term 'carplay connectivity' feature. without being able dig deeper carplay documentation (which restricted mfi enrolled developers only) left speculate if carplay right term. external display + car input + audio explicitly not requested. doubt carplay correct term, can not 100% sure.

i have developed iap2 on bluetooth , want use same iap2 protocol on usb.

so questions are:

  1. what difference between carplay , pure use of external accessory framework?
  2. is there difference between externalaccessory on bluetooth , externalaccessory on usb concerning entitlements , declaration of iap2 protocol identifiers?
  3. how wireless accessory configuration capability related carplay?
