As far as I know you can stream as well as talk to passenger on most of the Cardo units. On the Cardo website, it showed that you can. I, along with two friends stepped up to the Packtalk from an older Cardo system. Another buddy has the Freecom 2 or 2+ I believe and we can talk and he can stream his music. For us to communicate I just change to Bluetooth instead of the DMC mode and all is good. On our 10 day trip in June, batteries would last all day and then we always charged overnight.
I do recommend Cardo products.
