not really, after an unknown turn of events the memory value jumped 4 bytes after several months on my machine. On LostReception's 2k machine the value is a few hundred bytes away. However, there are clues as to where it is located. On machines configured the same way, the value is always in the same location. Obviously settings and system variables are what change its location, the question is which ones and how do we anticipate this?
At one time I located a value that signified the port my GPS was connected to.
I've also found a value that become either 254, or 255 everytime the Speed is recalculated....and this value always seems to be exactly 3 bytes below the speed address
