I've just noticed that my brand new DR750s-2ch only allows me to save up to 3 hotspots data (eg.: home garage, work place, my mobile's wifi). Would be great to add some kind of extra option to enter temporary wifi connection point's SSID and pass (just before leaving the car). This would be helpfull in the situations when my car is occasionally parked in places with free wifi (like shoping malls or hotel parking areas). Increasing significantly the overall number of passible to save wifi networks solves the problem even better. Seems not very hard to add this in new upcoming firmware versions.
