    FYI. Checked the Garmin site and update 4.00 is out for the 478.
    3 things

    - Improved XM wx data display algorithm
    - Added support for GXM 40 Ant.
    - Improved battery guage accuracy

    Interesting. Includes the NavTraffic reception - for $40 more than the GXM 30.

    Can you advise where you saw this? Even though the update adds support for ours, all I could find was it's only for the 690 & 640 units.

    I did a search on the Garmin site for "gxm" to find something on the gxm 40. I then went to GPScity.com to see if it was available yet. I found retail pricing over there.

    That is interesting. I've heard a few rumblings that the XM customer service people are telling callers that the NavWeather is available for the 478. Maybe they were just a bit premature.

    I just downloaded software and upgraded my 478. We'll see how it works over the weekend.

    this garmin page doesn't say the gxm40 is compatible with the 478 .....
    just the 640 and 698 (under products tab)
    https://buy.garmin.com/shop/shop.do?pID=15004


    download page:
    https://buy.garmin.com/shop/store/downloadsDetails.jsp?id=1503&product=010-00543-00&cID=148&pID=402
    but it does indeed say it's compatible here!

    now why would I want the GXM 40 over the 30?
    I bet I could find a 30 much cheaper than the $ 267.84 USD for the 40!

    dang, no "compare box " for the 40 here:
    https://buy.garmin.com/shop/shop.do?cID=203

    the xm page isn't updated either for the 40
