Well my firmware is 8.3 but that depends on the language version you got, mine is Dutch. So you got to find somebody with the same language.
About home 1/2 you have to enter your home-adress then go to lhe listing 'last destinations' select one (your home1) your nav shows then the'POINT' (the adress on map) sort off cross then you can select button home1. So the button is active, when you use the little buttons under the'H1' you select your home adress then enter nav will ask calculate route? and there you are.
I hope it's not to complicated and I don't know the terms are the right ones in English.
