Except for the (missing) features on Android for Garmin Pilot it worked perfectly for my Thanksgiving trip. On the way out I used my new iPad Mini Retina, connected it to the Delorme inReach SE and my headphones to play music, but would never consistently connect to the GDL-39 for more than 30 seconds. Pulled out the Galaxy Tab 8.0 and worked perfectly for the GDL-39.
On the way back I used only the Galaxy Tab 8.0 with the Delorme and Bluetooth audio for music and the GDL-39 and it all worked perfectly.
