Help please

My Galaxy s7 is suppose to arrive today.I don't like mirrorlink because I don't like having to always hook up a cable.My head unit is the Avh x3700 Bhs.Does not have hdmi input. Could I connect usb cable to a bluetooth dongle and then wirelessly connect my phone. I couldn't use an "usb to hdmi" cable cause that would require wifi. Suggestions anyone?
