Can anyone help me clear up my confusion. I am about to purchase Navman's smartST V3 with Oz maps for my iPAQ 2210 running pocket PC2003, with a CF GPS receiver. I will be heading to Europe on a few months time and am looking to also get maps for western Europe but am not sure what will work with my (soon to obtain) smartST V3. I obviously do not want to pay the Navman price, and have found ebay sellers in Europe selling maps that apparently will not work for me cause of registration keys....... I'm confused!
