The dealership where I bought my car advised against having the dealer-installed option put in my car. They said there have been a significant number of issues and complaints about the unit, especially concerning the reception.

What I've done as an interim measure is put the antenna on my back window (inside) and run it to the center armrest in the front, where I've hooked up my Sirius unit to the power supply and the iPod input. I can't see the unit, but I know how to feel my way around it to change the station. Not a big deal for me as I typically only go between BBC World Service, BBC Radio 1 and Dallas traffic. What I did not expect, however, was to have to endure this temporary solution for an indefinite period of time.
