Hi All,
After plenty of buggering around, I've managed to sort out how to scan and import my Rooftop's paper maps into the Memory Map application and Hema Navigator on my iPad. So for all of you folks using those applications and who have never tried importing your own map, here comes my step by step guide on how to do it.
There is precious little information on how to do this out there on the interwebs so hopefully it can save someone else the aggro it has caused me because there are some tricks to it that aren't documented anywhere.
I also plan on undertaking a similar process for importing and calibrating into Maps n Trax, but first things first.........
