Great thanks for the update/recent information [MENTION=311058]golfmad[/MENTION] & [MENTION=804859]plunet[/MENTION]. Will be testing it end of March. After stumbling across this thread and the suggestions several times in my search for a solution, I have finally decided to buy and test the device. Thanks again for the hint and the idea, that would help a lot in the future, especially on the BA legs!

Edit/Update: First use on board of QR, works like a charm. Looking forward to BA/AA during next days. Thanks again for the tip, it helps immensely for the (sometimes necessary) simultaneous work on several devices!
