This will turn your navman into a PDA and unlock it so you
can add tomtom or what ever its very easy to do provided
you have an SD Memory Card and a SD card Reader for your PC,
SD memory cards are cheap on eBay, I forgot to add to the
instructions in the torrent after you have unlocked the
Navman to delete what you have put on the SD card as it
would have installed on the satnav.
