That actually brings up something interesting. I have a gen1 stratus and was using it. However, due to low clouds I wasn't ever any higher than 2500 MSL and I don't think I was getting good signal. I was getting METARS/TAF data but radar wasn't loading properly... I just saw large blocks where it was trying to draw radar but it just wasn't good enough to be useful. I have little doubt if I had been able to climb a little higher it would have worked fine but I didn't really have that room without doing a lot of cloud dodging if I could at all.
I knew there were some low ceilings along my route and some activity near my destination when I left. I'd figured there was a good chance I'd do exactly this before even starting the engine. I really wanted out of Chicago and I figured if I only got halfway home that would make it more likely I could find a gap to shoot the next day. The first part of the trip went pretty much as expected, cruising 2000-2500 to maintain 500 below. Up ahead things looked darker... not scary dark but darker and I knew storms might be ahead. That's when I found my ADS-B had failed me. I pressed on for a bit, pulled out my phone and found a 3g signal and opened foreflight on it hoping for radar data that way. About this time I noted a nice big runway a couple of miles off my right wing. Took few miles to get a radar picture as cell signal was poor and about this time the airplane was starting to get tossed around a bit. This was making it hard for me to hand-fly, operate the phone, and consider my radar picture at the same time and that was sort of the last straw. I decided I'd better just turn around and land on that nice big runway, then I could safely pull up some weather and consider my situation. If it looked OK still, I could just take off again and continue. If not, then I was on the ground.
I'm posting this from a motel room. Thing is this is only my second trip more than an hour from home as a private pilot and the worst weather I've taken off into. I believe a more experienced pilot might have picked their way through this safely but I didn't feel confident that I could spot a thunderstorm ahead with an overcast ceiling barely more than 500' above me if I flew into rain with reduced visibility.... and I promised myself and my wife before I started going on these trips that I'd be a big chicken and err on the side of caution with these things. So I think I made the right choice. Sure would like to be sitting with my wife and playing with my puppy right now though.
