...I find phone based apps useless anywhere except in cities where there is plenty of coverage to run them.
I guess I didn't explain myself well when I brought up the subject of the two iPhone weather apps in post #88.
I've got a Zumo 590, and it has the capability of fetching textual weather information and generating weather graphics. In fact, the device is pretty clever about how it displays this information... if you have a route active, it will show weather information (both actual and forecast) for the cities along your route, which is a nice feature. But, despite the fact that the Zumo 590 will do this, and despite the fact that I enjoyed pretty good cellular connectivity during my recent ride from Toronto to California, I didn't make much use of the weather information on the Zumo 590 because I found the weather information on the two iPhone apps (WeatherPro and MeteoEarth) to be far superior in every way to what the Zumo 590 presented. In fact, the aircraft that I flew regularly (shown above in the picture in post #94) would fetch aviation weather in both textual and graphical format via the XM satellites (assuming I was over the continental USA or Southern Canada), and I found that the weather information on the two iPhone apps was also far superior to what came through on the aircraft system. That's saying a lot, because the XM weather for the aircraft was expensive (about $100 a month, if I recall correctly), and I was the person who designed and specified the whole avionics system (including specifying the weather service) for that aircraft before it went into production!
I very rarely use the cellular telephone system to fetch weather information via the iPhone apps. Just about every place on this planet that I sleep in, eat in, or relieve myself in has Wi-Fi connectivity nowadays. In the morning, or the night before, I fetch weather information with the iPhone apps when I am at the hotel. While riding during the day, I can fetch weather information anytime I stop for coffee or fuel.
For us as motorcyclists, weather forecasts are strategic, not tactical. In other words, we're not navigating through a line of thunderstorms on a minute-by-minute basis in the same way that an aircraft does, which means that we don't need instantaneous, high-res depiction of what is directly in front of us. What we need is an accurate and trustworthy "big picture" of the weather systems around us in the morning, before we set out, and periodic (meaning, every 2 or 3 hours) updates showing precipitation - most especially convective precipitation - as we ride along during the day. I get all that from the iPhone apps. What is most valuable to me is graphical
forecasts (not current depictions) of precipitation, surface winds, and temperatures for the present day and next day. Neither the XM system nor whatever the Zumo 590 uses provide graphical
forecasts. They provide graphical depictions of
what is happening now.
I'm happy with the Zumo 590 as a GPS navigator. I think it's worth the price paid just for the navigation features, and a few other features such as quickly looking up the next gas station or hotel along the active route, playing music, displaying traffic info around big cities, and delivering phone audio to the helmet headset. I'm not certain that the weather information that is delivered by the Zumo 590 is equal or better to what the Zumo 665 delivered from the XM satellite. If weather information from the Zumo 590 is important to prospective purchasers, I suggest you very carefully evaluate the quality of the information provided (in real time) by looking at someone else's Zumo 590 before you lay your money down. But, having said all that, I don't think weather via the Zumo 590 matters at all, because I get far better weather info from the iPhone apps (via a Wi-Fi connection when I am not riding the motorcycle).
