So, to install maps on a device [i.e. create an image file] only MI is used, and the data it uses to do that is in the gmap folder installed in your PC [hence the term 'PC Install version']. The gmap folder data can also be read by BC, but it cannot compile/instal/send an image to the device, to do that it invokes MI, however to a casual user although they may appear to be 2 parts of the one program they are in fact 2 completely separate stand-alone programs. You can use MI to instal maps on a device or card without first starting BC, and BC cannot do that directly it must call on MI to do that job from the PC installed gmap data.
So in essence i think you've been confusing what can be done using an image in BC, and further not grasping that a complete working image can only be compiled from the gmap folder data using MI [not BC].
Now what you need do is download a PC install version [or just the gmap folder]. Run the installer to fully instal or just place the gmap folder according to your OS. See the links given previously. At the risk of Caty & myself repeating ourselves:
The image file on your nuvi is too big to be seen by the device itself. It can be seen by BC but BC can't do anything with it in the way you're wanting/expecting.
