Installed the Mediabridge last night, seems to work pretty well. Only gripe is the navigation through functions and menus. Little slow, but does what is advertised. Ipod navigation sucks but the sirius function and bluetooth work great. Install was fairly straightforward, longest time was spent routing cables and wires and having a clean look.
