Wouldn't it be more useful to check whether sending the approximate location in the initialization sentence helps the startup time?

In my particular case, the receiver already has the approximate location at startup. It doesn't need any help from the software application to do this. The instant the software starts talking to the receiver, it spits back its last recorded location as Lat/Long coordinates. So my particular receiver doesn't need this information.

Seems as though all it needed was the appropriate instruction to just boot quickly (using the existing stored information from its last session) instead of cold-boot.
