    GPS not detected

    I'm using my GPS that I used for my XDA. Its a normal wired gps with the xda end for the connector. So i looked as to what wires were used and then cut off the xda conenctor. I replaced this with a usb wiring up just the data- and data+ because the GPS is powered by 12v so theres no need to hook up the usb power.

    I've plugged this into my PC (via usb) but MapMonkey cannot find the GPS. I can only look for it on COM port 1, is this correct?

    Protocol is set to NMEA
    Baud Rate is 4800

    When I first start up MapMonkey loading Destinator 3 maps it says COMM PORT DOES NOT EXIST.

    Can anyone help me with this please?

    BTW gps is turned on and working properly.

    It's very likely that the connecftion to your XDA isn't a USB connection, so hacking off the XDA connector and witing up a USB connector will work.
    Have you looked in the FAQ yet?
    How about the Wiki?

    The GPS had a data in and data out going to the xda connector. So I am assuming this would correspond to -data and +data on the USB connector.
    The XDA comes with an xda to usb lead and there is no circuitry in the lead to converter or anything.
    I jsut tried switching the 2 data wires around just to see if I had got them switched wrong but this didn't work either

    And what are you going to do for drivers for the unit?
    Is Windoze even detecting this cobbled-together unit you have? I'd be surprised if Windows even detects anything.
    One thing that every Windoze-compatible device has is some sort of ID to tell Windows what type of device it is. The drivers also reference this ID.
