I have had a Tracker system on the caravan since new, but there has been a series of ****-ups which leave me with very little faith in the Tracker company. The first year was included in the van purchase, but it turned out it was never registered, so I got the second year free. At the end of that year I got two renewal demands for different CRIS registrations - this took ages to sort out. In the end I renewed the subscription for £39.95. I have now received a demand for next year's subscription for £89! The Tracker website gives the annual fee as £39.95 - it looks like they are trying it on! Anyone had similar experiences?
