Got the 1030 this morning. Good timing it appeared to be as the GPS and altimeter on my 1000 seems to have crapped out.
Started the setup process following the prompts and things seemed promising. Got half-way through the phone/1030 setup and the connect app on the phone hung up. Hung up the phone so well, it froze the full screen. Even the on display time of day froze!
Finally after 4 or 5 tries (deleting the blue tooth devices, unloading the Garmin connect app), I was almost able to get it set up until the Garmin app hung up again when getting my profile info. The Garmin app is really brutal and needs to be looked at by a qualified Apple app developer. They are doing something wrong since this is a simple question and answer situation and the phone case is burning up! They are doing something really stupid in the app to cause the battery to drain really quickly and to cause it to heat up.
Next problem was adding sensors. It found the speed sensor twice and interestingly named it twice (not sure what happened there since I only named the sensor once). Then it wouldn't find the Di2 at all. Five minutes of trying to get it to find is five minutes of time I am never getting back. Finally, I used the e-tube app to update the Di2 firmware just in case it was that. Eventually, and for reasons I do not know why, I was able to find the Di2 and get it paired with the 1030.
What should have taken at most 20 minutes became 90 minutes. Hopefully the rest of the setup doesn't go totally sideways.
