A friend of mine wants to swap his navigator 2 for my quest 2. He has owned it for one year, used it once and said he could not get used to using it. It has v6 mapping. With me not knowing much about gps, would it be worth me doing the swap? Mine cost 480 pounds with bike holder. He also has the bmw power lead. If its worth it, would I be able to get v8 mapping for it? Is it easy to use? As the quest is very simple. Or should I just stick with what I know? He said he payed 1100 pounds for it. Thanks for your help.
