Have you tried telling Power Amp to wait until media is loaded before restart? Seems this might help with part of the OP problem. Also, I hate the look and feel of the A2DP "app" on the HU so I don't use it. I load apps directly to the HU and use it as it's own device for media/streaming and this eliminates lots of issues, for my set up anyway. I have a dedicated hotspot for the car but you could use your phone via tether, whatever your Hu supports.
