Parrot hands free will accept mobile calls when set to auto answer without touching your mobile.
Natty toy & keeps me legal, rather than trying to drive & use a mobile as we all see other drivers doing.
I had an old 1 in shed, so may as well fit it to car only half a dozen wires to connect.
I'm not smart enough to make the period radio auto mute though, so i will just have to turn it off if the mobile rings to avoid feedback
