I actually just have it in my middle console. I bought the sunglass holder to replace the the ashtray but just haven't had the time to do the integration. Kind of waiting on Howard to make his decision b/c if he doesn't resign I'm cancelling my membership and will just take the sirius out of the car altogether.
But if you plan on keeping it I would suggest doing the sunglass holder option, with a small orange display and you can conceal it by shutting the lid.
Let us know what you decide!
