Avin Avant 4 - No Answer from Control Unit error

For those of you that have installed the Avin Avant 4 in your X5 w/ DSP, did you ever get the 'No answer from control unit' error when trying to unlock the IBUS unit?

I've been back & forth with Avin support since I bought the Avent 4 in May, and we've tried everything from installing software updates to replacing the IBUS unit. Weird part is that the head unit seems to recognize the unit attached to the USB, and then it doesn't.

Anyone been able to resolve this?

Thanks in advance!
