Jim,
Maybe the unstated part of the solution that makes it work is that it is a
Magellan, as you mentioned in your original E-mail. Or one of the other
off-brands that are not designed with as much forethought as some. Remember,
the functionality that you are seeing is strictly in software, not a
component of the GPS system at large. You only tested one model of one
brand; it is entirely possible that some work as stated. :-D
