It worked just fine for 2 years with a Samsung Galaxy S5 for bot TEL and Audio. I removed the device (S10) and reconnected resulting in the same: phone for calls but no audio. Not sure what else to try.
I have found the Bluetooth pairing on the Kenwood to be extremely frustrating. I recommend you clear or delete any previous pairings. Then restart the Kenwood and try again. It might take more than one try. But once a device is paired it seems to work OK. I use it for audio books on an iPad when travelling.
Also I doesn't seem to handle multiple paired devices well.
