I can't enter my phone book from my htc phone

[AC Question]

HTC phone will not transfer phone numbers to Bluetooth on my subaru

Welcome to Android Central! Which HTC phone? When you first paired the phone, do you recall a prompt on the phone asking permission to share contacts? If not, try forgetting the pairing, then pair it again. Also, go to Settings>Bluetooth, ​tap the gear next to the car system, then make sure Contact Sharing is checked on.
