UP-DATE: I always seem to run into "odd" problems. Apparently no one on this forum has experienced anything like this, as there have been no replies in almost 2 months. For those who have stopped in, here's more to the story (most of which I posted in a more recent thread).
The problem was caused when I inserted a
COPY of the latest version (v.4.9A) of the "White" GPS DVD.
Apparently the system detected the disc as "illegal" and aborted the install/load. When I went back to the OEM "White" v.4.31 disc it would not re-load either. Learned that once you up-grade you cannot go back to an earlier version. In trying to load the v.4.9A, the system evidently recorded the attempt to up-grade and has locked out my original disc.
BEWARE of unauthorized DVD disc in Honda Navigation System. The system is apparently much more sensitive than a PC.
