What does not work well is, for example, the automatic change of the route calculation between online and offline (BRouter) when the internet bandwidth is low. I had already noted this as a point of criticism in Kurviger 1 and it still does not work in Kurviger 2 and proposed a timer (20 sec for example) when a route couldn’t be calculated, then switch to brouter and calculate again. For a further calculation automatically use the standard setting again. If this is Kurviger + Brouter, then try online first, if again a route isn’t calculated in 20 seconds, switch again to Brouter offline calculation.
Until this is working or if it is too difficult to realize, it would be advantageous if the data connection could be switched off and on via the Kurviger push button in order to force the calculation via BRouter, because it is not possible to do this via the usual methods while driving, especially not when the smartphone is in a cradle.
