My touchscreen calibration has slowly drifted over the months so that I am unable to select some of the icons on the left of the screen. I have tried to recalibrate it but it just continues to move the cursor around the screen as it normally would except it never stops (finishes). Previously it would move it to the various positions as I put my finger on the little crosses and then go back to the main screen. Now it never finishes - just continues to place the cursor, move to the next position after I place my finger on it, etc. I have followed the cursor around the screen as many as ten times and it just continues...

Help!

Suggest you check out this http://ifly.adventurepilot.com/SUPPORT/Forum/tabid/108/forumid/6/threadid/15662/scope/posts/Default.aspx thread for a solution from Adventure Pilot's excellent support staff that is still working for me.

Dick,

Sometimes if the iFly is put away with something pressing against the screen, it can cause some issues. We've suggested for several pilots to try the below and see if it helps. Seems to help, the unknown is for how long, but it is definitely worth a try. If it works, I would definitely try to store your iFly without anything against the screen.

Try this: Power on your iFly GPS on the AC power and place it screen down on a flat surface like a desk or table. Leave it there overnight so it can build up some heat on the screen. Then in the morning, unplug it, leaving it face down for about 30min to an hour so it can cool completely. Finally, flip it over and power it on and try the calibration. (this basically helps to reform the touchlayer, as that might be causing the issue)

It's possible this could fix your calibration issue, but there is no guarantee that it fix it long term. If it does not fix it, it will most likely need a touch layer replaced. Give us a call at 888-200-5129 to get an RMA. I hope this helps.

All the discussion regarding a similar problem notes that the phenomenon is somewhat unexplainable. Okay, I can buy that. However, my problem seems a bit different from the other comments.

As I said earlier, the buttons on the left don't work any more - the sensitive area seems to have been slowly drifting to the left until now they are off the screen.

Doing the powered flat on the desk seems to have helped a bit with the buttons - some of the ones on the left now respond. I am going to try that again, but it definitely needs to be calibrated.

However, when I go to recalibrate it, it responds to the touches to the crosshairs just as it always has. It is just that it never stops the calibration procedure - just going round and round showing the five crosshairs and then moving on to the the next after I press on it. This seems different from what others have said. Unless I am misunderstanding, theirs would not respond at all to the calibration presses. It makes no sense to me that if it can sense the presses during the calibration procedure why won't it recalibrate??? This just doesn't seem like a hardware problem.

It hasn't been lying against anything as I have been keeping it on my car dashboard (since the weather has been too miserable to fly up here). That does mean it has been vertical for some time.

If I get the touch layer replaced, what prevents it from having the same problem again? Has the new touch layer been redesigned/reformulated to prevent this problem?

The behavior you are experiencing (failure to recalibrate / stuck in recalibration loop) has, in fact, been experienced numerous times by others. It is a known hardware failure mode, and if other recovery options (like the overnight bit Shane described earlier) are unsuccessful, then a replacement of the touch layer may be required.

My screen touch accuracy gradually degraded over a long period of time to the point where recalibration could not be performed and the unit was no longer usable because I couldn't press certain buttons, like you are experiencing. I finally sent my unit in, and the touch layer was replaced, and the unit is back to good as new. (During the process, I learned that I have the first 720 shipped to a customer!)

I had similar issues with my Palm V and Vx PDAs back in the day, which used the same touch screen technology. I'm afraid it's an unfortunate drawback of the technology chosen for the touch capability. It seems the tradeoff is essentially sunlight-visibility in the cockpit (the iFly's resistive screen excells here) vs. touch layer stability (capacitive touchscreens used in other tablets do not have the calibration drift issues that resistive screens do).

I now fly with both a Nexus 7 and the iFly 720. I now generally prefer the Nexus, and typically keep it on my yoke, with the 720 on the co-pilot's yoke. If I'm going to be flying for a long time with the sun coming in my window and washing out the screen, I'll swap 'em and use the 720 on my yoke.
