I had a little difficulty connecting it to my Garmin at the beginning. Some on the internet pointed out, the problem was due to the unit being inside the frame. I just removed the seatpost put the garmin next to the wireless unit, hit the Di2 icon on the screen and VOILA!

Thanks to everyone for their recommendations and advice!
