    Thus far I've side-stepped legendary compatibility problems with hooking my
    Garmin 48 GPS to notebook PC by always using 9-pin serial port. Never had to
    experience the trial and error of of USB connection.

    As everyone knows, it's getting to the point where virtually no low-end
    notebook PC's have 9-pin serial ports.

    Has this GPS-USB hookup problem now been reliably addressed by whatever
    means ( XP op system, Garmin software, etc)???

    Comments would be appreciated as I'm getting to the point where a new
    notebook PC may be in my future and it's unlikely to have 9-pin serial port.

  2. Faced with the same problem on my new laptop, and a usb-to-serial converter
    that would work fine with Win98 and Win ME, I thought all I had to do was
    load the software to my Win XP-Pro machine.

    Alas, the OS rejected the drivers, and gave dire warnings that the laptop
    might explode if I proeeded to load the older driver.

    A search through the Net revealed that the driver manufacturer had been
    taken over about 4 times, eventually finishing up as the subsidiary of a
    subsidiary of Intel. Result- no drivers for Win XP.

    I went onto Ebay and found a supplier of new usb -to-serial converters, with
    a WinXP- compatible driver, and am pleased to say all is well! My new laptop
    works with my Garmin, no problems. Cost me about £15UK.

    Remove "nospam" from return address.
  3. Get a cable that is USB at the PC end and Serial at the GPS end. I saw one
    advertised in today's paper, probably at Fry's. If they have it, any PC
    place hould have it.
  4. Didn't know there was such a thing! TheGarmin plug wired to a USB plug?

    It is not uncommon but more often the rule that a USB to Serial Driver does
    not have the M$ stamp of approval. I have installed numerous USB to RS232
    converters and have yet to find one that comes with a M$ certification. I
    just ignore the warning and install the driver. Never ever had any problems.

    We use the laptops for industrial Automation Control systems and I used it
    for connecting a new laptop to an old GPS II.

  6. I find that most, if not all USB/Serial converters have drivers for both
    MacOS and WinDoz (98-XP) available on the net. I use them all the time
    for GPS connections and other serial type connections, and they work
    very well for me.

    maybe that will help

  8. I tried this (ignoring the warning), but the driver refused to work, and I
    got frequent warnings about the driver file from WinXP, so I deleted it.

    The new one works fne.

    Sounds like you had some of the hair pulling "fun" I too have enjoyed with

    Congratulations. Glad to hear it worked out for you.

    There has been a lot of interest in adapting Garmin GPS to various
    ports. I think Garmin has two or more proprietary plugs called
    something like the "eTrex plug" and the "round four pin" plug. There
    are adapters for those to DB-9 and USB serial ports. A web search will
    bring up a lot of info on this:

    I've been using a Keyspan USA-49W under XP with no problems.
