PUMPKIN CAR STEREO SUPPORT CENTER

Hello,
I have a new problem:
When I try to connect my new phone with bluetooth, a connection is established but the telephone connection breaks after a few seconds off.
Then, reconnected and then canceled, etc.
With the old phone it takes also a few attempts but after a few tries the connection was stable.
I made many tries with the new phone but no success.
A reset of the radios has also brought no success.
The new phone (Android 6) connects with other recipients without any problems and stays connected.
Why it works not with the radio?
Model: C0255 (S07)
Firmware is from the link that you send to me on April, 13.

Thanks and regards

Hi, about the bluetooth connection, if you had pressed the RST hole to reset the unit, please enter the setting-->backup&reset-->factory data reset to restore the factory setting, then please check if your phone have the limitation settings for allowing the external device connection and reboot your phone to check.
As you described, the unit could connect to you old phone, and your phone could connect to other device.
Maybe the unit is not compatible with your android 6 system on the your phone.
Regards
