I need help please. I purchased my ZUMO unit ,with Europe maps, CD etc, managed to unlock them and all good, and I have no problem creating routes etc. However I have purchased a Micro SD card with Middle East and another with South Africa maps but I am unable to read either of these maps on the Basecamp or Mapsource software on my laptop and am therefore unable to prepare routes in these country locations. Can anyone tell me why I cannot read the Micro SD Card Maps on Basecamp or Mapsource. Thanks.
