I'm a little late on posting about this, but last week the version 1.1 update to C2G became available, which fixes the crashes that Vancouver customers were seeing for a couple of days.
The crashes were happening because the data coming from car2go about available vehicles in Vancouver contained some invalid location information for some vehicles. I wrote to the car2go tech people about this, and they actually fixed the problem on their end, which stopped the crashes in C2G. But in case this kind of thing happens again, version 1.1 of C2G includes error checking code to prevent crashing.
Now, if I could just get in contact with Jeffelliot, who experienced such a crash right after he bought C2G :( Jeff, I fixed it! Please give me a better review!
