When I wanted to add Sirius to my '07 stock FEH Hybrid stereo (no Nav system), I was shocked to find out that it would cost $538 to have a simple Sirius tuner installed. When I said that it would cost me less to replace the stereo with a better stereo AND buy a separate compatible sirius tuner, the Ford Install guy at my dealership told me that if I did that, I would void the warranty on my vehicle.

I called Ford and was told that if I replaced the stereo at any place but an authorized Ford dealership that I would void the warranty in regards to any problems with the electrical system in the future that I could NOT prove without a doubt were not due to tinkering with the stereo system in the FEH.

Has anyone else who has replaced their stereo system checked it out with Ford ahead of time?
