Randy Regina, Sask Jun 8, 2011	GARMIN GXM 40 XM SMART ANTENNA Pros: works fine with the zumo 665 Cons: no use having 2 antennas - as 1 won't work In my case, this unit is only useful as a replacement for the same antenna that came with my Zumo 665. I tried to get my Zumo to work with both antennas (i.e. - one in car and one on bike) and it wouldn't do it. In order to get my Zumo to work in the car with the second antenna, I had to get XM to send me a new signal. Then when I want to use the Zumo on my bike, XM has to send me the signal again, as I switched antennas. TOO MUCH TROUBLE! Recommend? NO OPINION 45 viewers found this helpful.

Mark Ocean Houston, TX Nov 3, 2010	GARMIN GXM 40 Pros: worked as planned. Cons: high cost prefer the product be white Matched this antenna up with my Garmin 640 to get live weather. Worked just as expected. Mounted it Handled alot of water without exception. Magnet holds well. This year the Harvest Moon Regatta had big wind and seas. Pretty nice having the information. All this info was available to you. I use it for boating offshore for sure and whenever I sail on the bay. Nice to have real weather information. If your cruising or racing for extended periods of time this is a great idea. Once you encounter tough weather then it will help you understand how long you will be exposed and the intensity. Another words: Oh sh.. or you are going to have a meeting with Jesus. It has all been decided.... Recommend? YES 65 viewers found this helpful.
