My boss was not too pleased when he found out my Superb has basically the same sat nav as his £150,000 Bentley Continental GT. He was even less pleased when I pointed out both cars are made by the same group, and there may well be other shared components under the skin.

 

Found this one on Autotrader, take a look at the nav picture http://www.autotrader.co.uk/classified/advert/201411078810520/sort/default/channel/cars/make/bentley/onesearchad/used%2Cnearlynew%2Cnew/radius/1500/model/continental/postcode/ex167ll/advert-type/featured-listing/dealer-id/734305/usedcars

   

There will be same units I'm sure, just as there are in other VW products, such as washer bottle, header tank, various electrics, fuse box, mirror motor units, seating motors and linkages...
