Toledo blue eh. Cool x5. The VIN comes up as an automatic though. Was it swapped at by a previous owner?

At any rate, VIN shows it was originally equipped with option 609 Navigation System Professional and 676 HiFi Loudspeaker System. So that explains why you aren't getting sound from your tweets. Let me put in a call and see what my bud did to rectify the situation.
