Setting up Ozi Explorer for PDA

Hi All,
I was wondering if I could seek help and advice from some generous member (preferably located in Brisbane) who is familiar with Ozi Explorer and its various uses.I am currently trying to set up Ozi Explorer software and configure some Hema raster maps for use on my PDA. I am familiar with other navigation programs (Copilot) but am having trouble coming to grips on how to use Ozi Explorer and would greatly appreciate discussing some of the issues face to face with someone who is familiar with the program.
At the end of April we are planning an extended 6 month trip in our 18' BT out from Brisbane across to Central Australia via the Strezlecki and Oodnadatta tracks and across the Tanami to WA and the various remote areas of the Kimberleys and Pilbara regions. It would be good to be able to use Ozi Explorer with at least a small amount of expertise by then.

Thanks in anticipation of someone's generous nature.

John
