No...not at all. What Chas521 is suggesting is to use a version of iGO or Primo
instead of your "Cityguide" software.

It sounds like your Cityguide software is locked to it's original SD Card (as many Retail versions of other navigation software may be).
There may be nobody here that is familiar enough with that particular software that can help you 'crack' it so that it may be copied and used on another card or device.
