Ford was using Motorola audio systems in the seventies too weren't they? My sister had a T.O.L. 1976 Ford Granada that had the optional Motorola Quadra sonic system in it. It was an 8-track player that would play 4 discreet channels. The speakers in the door and the back were 2 way speakers with tweeters. The system sounded quite nice, and sounded better than even some of the aftermarket systems of the time.
What I also thought was interesting about this car was that it had a G.M. A6 compressor on it with the "frigidaire" name and logo on the top of it!
Although GM sold the frigidare division to WCI, they held on to many patents like Pete mentioned. One of the most interesting is the rotary compressor designs that were used since the 40's in most of their fridges. They sort of work like a wankel engine. They have a unique sound to them that is unmistakable. Only recently, in 1996 I believe, have these compressors been re-introduced to the HVAC industry since the patent ran out. They are touted nowadays as being high efficiency compressors and a "new technology". Ironically, the American manufacturers didn't pick it up, but is yet another case of an American design going overseas, as Panasonic and Samsung are the two leading companies using that design.
