This Application originates in the UK. It is extremely powerful but not as intuitive as we are used to so you have to read the instructions to get full value!
There is a free trial version; the extra functionality of the full version is worth paying for. It interfaces with Autoroute Express too. But as you don't say where on the planet you operate, this may not be much use.
I haven't tried others; this does all I want in preparing for a trip and downloading after a trip.
