IIRC from school, BT's range is suppose to be a max of like 20 ft or something like that... so your visor should be just fine for streaming audio. I agree with critcal, I've seen some phones works great, and others suck hardcore. Best thing is just to make sure your radio's BT firmware and your phones software are all up to date. If possible try a demo car/radio before purchasing to make sure your going to be satisfied with the out come of your purchase. In the aftermarket, I know companies like Kenwood have a compatiblity chart for their radios to check if certain phones will work.
