Bluetooth disconnecting from car

[CliveMythos]

1. Model Name: RoG 6 512GB
2. Firmware Version: WW_33.0610.2810.166
3. Rooted or not: Factory standard
4. Frequency of Occurrence: Looping

So as the title suggests, whenever I attempt to connect my RoG 6 to my cars bluetooth audio, it'll disconnect and reconnect, looping (connects, disconnects, reconnects, disconnects, reconnects, keep going till I turn off BT from the mobile)
Cars a Mazda 6, phones the RoG 6 512GB Black. 

Tried clearing the phones cache, reset the phone, cleared all connections to car.

do you try to connect other device to your phone or to your media

[CliveMythos]

I can successfully connect another Samsung phone to the car no problem. Have successfully been able to connect edifiers, logitech, and XCD speakers to my phone no issue. 

It's just the RoG phone to the car that isn't connecting.

The thing that you can try and maybe can help is to go in development option and find this Bluetooth option

 on Bluetooth AVRCP and MAC change this option to Default restert phone and try again i dont know will this help but try and write again

Just attempted this after applying bluetooth settings to default and restarting the phone, but didn't manage to work. 
Went one above and removed the device from the car and the car from the phone, before reconnecting it with no success.
