No sound from car speakers, after 9.2.1

after installing 9.2,1 on my 5S and 6s , my hands free does not work properly

i have 2 cars , with 2 different original gps/Bluetooth systems

vw up 2013 - mapsNmore w org Bluetooth

skoda Octavia 2010 - Columbus gps w org Bluetooth

i deleted all connections

rrestarted all units

tried hard reset on 5a

i can easily find all units, and connect with PAR code.

but when phone rings, the sound does NOT go out through car speakers

even thoug at sound is set to "Vw phone/ skoda phone"

- if I switch to iPhone/speaker, the sound is as normal, but if selecting the car, then no sound is coming from speakers, and the microphone is not sending sound, to the person calling.

my 5s and 6s worked PERFECT on al versions BEFORE 9.2.1,

i have had these cars/systems for YEARS, with no issues.

PLease fix this bug

i cant use my phone in the cars !!!!
