On my 07 I presently have both his and her Nolan helmets with J&M hardwired speakers and mic via BMW com 2. I hard wire my Zumo 550 to phone jack in oddments box as well as the i-pod to aux jack. This works OK. Getting ready to purchase new Helmets and com equip. I am completely audiophile challenged. I have read many threads on different BT vs Hardwired systems that guys use but I am not clear on the step by step mechanics of hooking what to where etc. I am looking for suggestions as to the easiest and least expensive way to set-up the following: Intercom, I-pod, phone, Zumo 550 and occasional radio. I am open to both hardwired and BT set-up suggestions. Again please explain the actual mechanics in detail as to how you do your set-up as I am a little slow in the electronic advances and terminology. Thanks in advance since this has most likely been asked many times before.
