I have used Solid GPS for years in my caravans and it has given me a real piece of mind knowing that if ever it was stolen I could get it back because insurance does not necessarily pay out enough to replace the van like for like. An added feature is an odometer on your Dashboard so you know how far the vehicle or caravan has travelled. Great for planning servicing on a caravan. I recently purchased another Solid GPS and again it works perfectly. I looked at a number of options to Solid GPS but they were not up to what I required. I thoroughly recommend Solid GPS to anyone who wants to keep track of their car, caravan or motorcycle, anything for that matter. Any questions are quickly answered online which is a bonus and great service. 10/10.
