Hi no need for a phone but can bluetooth your phone using there free app off Google play, enables you to press a button on pure 400 unit and it saves the song for you ,free for a year then a small charge,doesn't let you use phone for hands free calls,it comes with a very small areal which sticks to top of windscreen that is attached to a black box just above ,twice size of a small box of matches, that has a magnet attached which slides under head lining to earth it,a wire goes down side of windscreen with sticky pads supplied, or hide it ,this is power supply for digital areal, goes in cigarette lighter,same wire has two connectors on it ,a USB and 3.5 mm jack USB goes in cigarette lighter using connector supplied or using another attachment can go in jack on radio,so connects straight to it,if you want it can be solderd into wiring behind radio for power supply and USB plugs into connector supplied so wiring out of way,pure 400 unit has a stand supplied with a sticky pad so attach we're convenient, comes with two aaa battery's which last ages,so no wires, plenty of instructions, if it is connected by jack it is a perfect connection so great sound,I've ordered a 20 pin to jack connector and female to female connector so hopefully will use this instead of jack input as radio doesn't have one,as it's digital it automatically tunes all stations for you like a TV then just turn dial until it shows station you want to listen too and press ,no tuning required.
