With the addition of new menus, moving menus around, or adding settings to menus its best to reset afterwards as well.

Make sure you do this with the unit connected on your boat so that the unit is in the Normal operating mode. Otherwise it will not remember the menu settings and therefore will not have actually reset the menus when you update it.
I can see no problems with this if the boat and transducer are in the water....

But, if my boat is in the garage.....and because the update install procedure you mention requires that the unit be powered on before the SD card is inserted into the unit....isn't the unit going to be in a "confused" state looking for a sonar return in the air by powering the unit on into the "normal operating" mode while sitting in the garage...??
