With the Speedo removed from the car I would test it with a cordless drill. Find a bit of metal rod and file a suitable square on it .
If that works connect the cable and put the cordless drill on the other end. If that works. Jack up one rear wheel. Crawl underneath. With gearbox in neutral revolve the propshaft with your hand and see if the speedo drive is turning. If not then there must be a problem with the skew gear drive which you will have to investigate.
BTW the Speedo on my pick up works but is hopelessly inaccurate so I always drive using my sat nav to indicate speed and miles driven.
