Another plug in module for it I am still testing but it gives the gateway BLUETOOTH
it has 2 modes
Hands free - yes its a hands free kit that plays through your stereo, on testing today it displays the number of the person calling you on the Boost stereo (certain years only) & you use buttons on the stereo/MFSW to answer/end the call
(mfsw with phone buttons not required)
A2DP - this is for the latest mobiles so you can play music from the phone via bluetooth & control it (track up & down) from your stereo/MFSW
