Since ive owned my car ive been using JetTech FM transmitters and it does a good job but being in NJ I cant take the little static in the background.

looked at the usa spec BT45 and it looks self explanatory but is the bluetooth clear and uninterrupted? I'm considering getting the aux cable for my S7 edge but if bluetooth works good I see no reason to add the additional extension

steering wheel controls now work and XM radio button now controls XM radio and BT45?

drop pin is up down up down I see.

anything I need to know or to look into before purchasing one of these?
