Caravan Club Sat Nav - Snooper S5450

Anner

Has anyone any feedback on this?  We've never used a Sat Nav before & I like the idea of being able to put in details of our outfit but is this really of help?  It sounds really splendid, but is a lot of money for us so I'd really like to understand what
the advantages and pitfalls are.  Is it easy to use?  Is the lane guidance easy to understand? And does it flag up those sites where we should use the Club's Sites Directory rather than Sat Nav?  Anything else I should know??
