Hello. We are using/learning to use TMM and an R2 GPS unit. We have had some mild hiccups, more so with Android than iPhone devices. On an Android device, we have to click the 'disconnect from the Internet connection' after enabling bluetooth, then close TMM before starting Field Maps. Field Maps will start TMM in the background, and all seems to be well. The iPhone is more forgiving in that one does not have to disconnect from the internet. It seems that if TMM is open and active and we try starting Field Maps, TMM throws an error regarding username or password being invalid, and then the connection to the GPS unit is lost. Here is a link to a short video we found very useful. I don't know if I have been much help, but wanted to pass along our experiences. Regards, Jay
