That's a setting for the rns510 - not a feature of v4 maps.
you can either turn on/off the option to "Suggest 3 Alternative Routes" at the start of each navigation.
by default, this is off.
its there in ur rns510 settings - under "Setup Navigation" menu.
i have that turned on on mine, and i'm using the v3 maps.
i too have ordered the v4 maps.....at a bargain price![]()
i'm not expecting much gains though. curiosity got the better of me.
