An antenna, software for the Axim, Maps/Charts and a Desktop/Laptop computer to load the information onto the Axim. You should also get at least one 512M Secure Digital Card for the Chart data. I have three for mine. A 512M card for my Marine Charts. A 1G card for my Topographical maps. (They work great for Lake and River navigation.) A 1G card for my street & HiWay navigator maps.
For my marine charts and topo maps I use Outdoor Navigator on my Axim. I believe it was around $15. I download the charts and maps for free
here. I don’t know why but Outdoor Navigator is no longer available. However they make another program Pocket Navigator that is much better for $49.95
here.. I may eventually upgrade to Pocket Navigator. The only thing bad about Pocket Navigator is, the Charts cost $$. To get all the charts and maps I want will cost me over $1,000.00 and Free is so much better, even if it doesn’t have all the features I want.
Check the two links above and if you want to use the Axim, I would be more than happy to assist, advice or help in any way I can. I have been using the handhelds for as long as they have been out.
Approximant cost - Antenna $150 - Antenna extension if needed $80
Cards $35 to $50 each - Software $50 - Charts $200 to $2000
