I highly recommend Art and his work. Crutchfield could not fix their own work and Art found the issue. Crutchfield instructions were not correct or complete. Two months and numerous module changes and programming and in the end, Crutchfield told me my head unit must be faulty. Nothing wrong with the unit or the modules. 2008 BMW with fiber communication needed to be set up in the cars firmware. He fixed all of the comm issues and the system works great. You won't be disappointed.
