webtech wireless receiver?
bought my m3 from a private party and i noticed that there is a small box on the corner of the dash that says "webtech wireless" on it. it has a wire coming out of it and it goes into the dash. i thought it was some kind of bluetooth receiver, but my car was loaded from the factory so there would be no reason for it to be added. googled the name and came up with webtech wireless as a telematics company. i emailed the person i bought it from and have not gotten a reply. anyone know what its for?
