Alpine uses a Parrot BT interface (FW version updated from 3.80 to 4.00) and it works fine with a Samsung S3 and Android 4.x via BT Phonebook App.
Same Car Kit with Samsung S5 and Android 5.0 and BT Phonebook App shows following misbehaviour (FW 3.80 as well as 4.00):
1. First Dialling attempt initated at the car kit with phone numer +4969123456 works
2. Terminating the line at the car kit
3. Immediate redialling attempt with the same phonenumber at the carkit cuts off the "+" and just transfers 4969123456
I tried all variations in BT Phonebook App for the number-format-settings and both profiles (PBAP und IrMC/SYNCH) without success.
Any idea? Thanks in advance!
describes the (probably) same problem with incoming calls.
