PUMPKIN CAR STEREO SUPPORT CENTER

Hello everyone, I'm new and I hope I have posted this in the right place. (I have not found where to show up and hope you can point it you kindly).

I have a problem with a pumpkin rk3188, some days it does not work more bluetooth, no way!
What may have happened??
someone Ever?

I tried to send an e-mail to the pumpkin, but they still have not answered me.
you know if there is an update that will solve this problem ??
thank you aid.

I post the photo of my firmware.

Hi,
Could you please first tell us your order number or buyer ID?
For the Bluetooth issue, please tell us more details about it.
Does the other person can hear you and the sound come out from car speaker?
I can send you the firmware for you system, but I'm not sure it can solve the problem.
