System 9 is Bluetooth hands-free car kits best friend .The idea behind System 9 is to hold your phone, charge your phone and connect it to an external antenna. Then all you have to do is connect your phone up to your Bury or pre-existing Bluetooth hands-free car kit. Using Burys interchangeable cradle philosophy System 9 is purchased in two stages; first purchase the generic base then, depending on what phone or handset you own purchase a cradle specific to that handset or an adjustable cradle. The easy cradle snap-in system allows cradles to be changed in a second, no tools are required and multiple users of the one vehicle can make use of the kit even if they have different handsets as long as they have the cradle to match their handset.
