I purchased Yatour BTA for Citroen RD4 in the spring. It worked just fine first, but now for two weeks there has been drop outs in sound. They happen very often, and sometimes my head unit even says that "source cannot be played". When I looked at bluetooth signal strength with my android phone, BTA shows very weak signal compared to other bluetooth devices (headunits own bluetooth for calls, obd2-scanner and so on). I think this is causing these problems.
Is there anything I can do to fix this? I just tried to unplug and replug BTA, but it didn't help. My headunit is Citroen RT5.
