I have it installed in my Saab. Still ironing out problems with my SWI-X remote adapter though. One bug I've run across:
When the program first comes up, the pause indicator is on but the song is playing. Hit the up button once and the play indicator comes up, hit the up button again and the player pauses and the song pauses and things stay in synch.

One future request would be to have a way to lock the volume at a level in the EMSC program. Other than that, things are working great.
