I need to connect a recent Garmin GPS (USB interface) to a BX-24 so I get decode the NMEA sentences coming from the GPS. I can do that without any problems with older GPS equipped with a serial port, but how can I do that with USB model? Are there any cheap onboard module that would convert USB to a serial with TTL levels?

I'm confused (again) and would love some help. I am still trying to get my GPS application to give solid data. I've ripped the app down to the most basic components (simply printing raw data from the input queue to the screen) and can't make sense of it. Below are two programs that _should_ do the same thing. The first one (Print1.bas) works beautifully. The second program (Print2...

You should just be able to talk to it using a serial connection. I think it's 4800 baud. I have one of the Parallax GPS units and there are two modes. The normal mode just sends out NMEA lines that you can parse with the BX24. And a smart mode, where you simply ask for the data you want. The smart mode however, is somewhat slow in that it has to wait for the NMEA line to pass before it resp...
