after installing metro on sd card and also installing pdb for city I open the pgm but city could not be found, is there a special place pdb must move on sd card

I recall needing to install the transit system databases onto the Palm/phone and then using the Metro program to move them to the card.

That's basically it.

Metro is a great program, by the way. I use it whenever I travel; both domestically and internationally.

what are these transit databases, please are they part of Metro system pgm list

When you download and unzip Metro you should have (in various languages) an application, documentation and a large file full of transit system databases for virtually every city on the planet that has a mass transit rail (and sometimes bus) system. You need to install both the application and the appropriate databases for the transit systems you will be using. I concur with the earlier post. This is a fantastic program that is continuously maintained and upgraded. I've used it from the start and I can't imagine trying to get around in a major city without it.
