Voice/sound is choppy when using car bluetooth

Hotelli

Hi,

I have problem using my car bluetooth handsfree. Receiving end work fine, the other person can hear me loud and clear but in my side the voice of the caller cuts randomly.

Here's the situation:

- Calls without bluetooth hands free work fine
- Bluetooth connection works OK (no sudden disconnetions)
- Contacts are transferred as expected
- Happens when Wifi is connected or disconnected, does not affect the situation
- Handsfree calling works fine with 2 different Windows phones and at least 1 android phone

Actions taken (not necessary in this order but you get the point):

- Updating the latest ROM (Super V3.02_20160923)
- Factory reset done
- Resetted bluetooth and wifi settings in the cars system
- Cleared bluetooth sharing cache
- Switched sim card positions
- Fiddled with volume options (both the car and Umi)

Next steps:

- Try some other handsfree
- Google some generic bluetooth/android/handsfree/potatoe solutions and fixes
- ?

Anyone else got similar kind of issues?
My main suspect is that there is some sort of defect in the bluetooth/wifi module (not plaming the firmware yet ;)

Otherwise the phone works like a charm at least for me but the handsfree issua bugs me alot.

I have the same problem: when I use the bluetooth in my car people ear my voice but I can't ear what people say.
Has anyone found a solution to this problem?
Thank you
Paulo
