This weekends was playing with NavCoder..... I don't know It is bug or...I don't know what else this could be.... after the diconnection the interface I found that Speed limit is fixed and swithed ON, date and time is changed and in the date all "0" are shown like "C", Aux vent is switched ON as well (on 11.00 ;-) )..... All this parameters are changing in Set menu without problems but....... is it BUG?
