I have a question about GPS receivers. I have MS MapPoint 2004 and I will probably be buying AGPS as well to complement it. The dilema that I have is that there are a bunch of different GPS receivers on eBay. If you were to search "GPS laptop" on eBay, there are a wide assortment. Would anyone be able to help and point me in the right direction as to which unit I should purchase so that it works with MP2k4 and AGPS with no problem. Thanks! As far as connection type, I could use USB, Serial (I have a USB to serial converter), or Bluetooth (I have a BT dongle). Thanks for your help!
