Information regarding speed limits and radars are also very well managed and relevant. They offer a real plus to the pipe.
However, the traffic info function is very powerful (hence 4 instead of 5 stars). Highway near large towns, I often have a smooth traffic information while I stopped in a traffic jam that lasts a good twenty minutes, cap announced by the motorway service (potentially unknown) and whose GPS never reported.
Apart from this, it does its job.
Obviously, it is not perfect, as all these devices. It happens that in some areas there is error mapping or GPS sees us on the small road located 10 meters from the highway. But this is rare enough not to make a generality.
And a GPS will never be as good as the local resident who knows his city well.
In conclusion, I am very satisfied with this acquisition, which has advantageously replaced navigation via smartphone, consumer battery, although less ergonomic and especially inefficient when the network is lost.
