For several months, my appradio 3 has worked perfectly. I am now finding that I cannot connect my A2DP and SSP, however phone capabilities connectos just fine. I thought it might be my phone, however am having the same problem with my note8 tablet as well. Can anyone point me in the right direction for correcting this? Ive tried doing a factory reset of the unit, however the [OK] button is always greyed out, even with the radio source off.  thanks!

Is the input source set to other for non Apple products?

Yes, it is set to "other"

Really can't think of anything that has changed. Just one day, it stopped connecting to allow Bluetooth streaming. Also will not allow me to connect through the pioneer appradio app or aru.
