Seems to work as advertised by routing to avoid routes not suitable when towing a caravan
Device rating - Cons:
Very slow updates time.
Although it shows which lane to be in when leaving a motorway or dual carriageway, it is slow to show the next turning and so often you end up in the wrong lane.
Mapping in the main is very accurate but as with a number of GPSs (I have several), local knowledge shows much shorter routes in several instances than the SatNav plots
