Have you received any reports of routing problems with the Toyota satnav? It is inconsistent, giving different routes for the same journey on consecutive days. Example - destination on the side of a dual carriageway- one day it will direct us directly, another day it will direct us past the destination to the next roundabout, back down the other carriageway then across the central reservation. Occasionally it will "move" the car a couple of miles at random - and usually it will recover after hitting a bump. It also ignores an obvious route, often routing the car via a diversion (the worst so far is about 6 miles instead of a quarter mile). I can get no help from the dealer unless I can demonstrate the fault which, as as it is intermittent, is virtually impossible.
