Hey Joe, what has Garmin said about the lockup's? I'd be a bit upset myself if a new-out-of-the-box system that expensive was acting up, and I'd call for a replacement under warranty!
Just FYI - I've had a 696 in my plane since before they were introduced, and have yet to experience a lockup (that wasn't caused by loading beta software).....

Paul that's a fair question. I'm trying to reproduce the problem so I'll know what to tell the tech guys when I call. So far, it has done it 3 times. Once in a hot cockpit while on the ground. Once inside the FBO running on battery power, and once in flight shortly after take-off. It's been extremely hot here and the cockpit was likely over 100f on both "in airplane" lock ups.
The instance in the FBO has me baffled. I was going to show my gps track coming home from Osh to the local airport bums, of which I am president

(cause I flew all over the country dodging storms) and I got the "software not found" or some such message that others have reported. The message is not documented in the manual. My new toy failed me and I was humilitated.

The FBO was a chilly 75 or so. Needless to say the bum crowd hasn't let me live it down.
The one time it happened in flight it just locked up with the page visible but with me unable to change to another page. If IIRC, I had moved the knob to the destination airport info page and it was "overlayed" over the map page. Rotating the knob would not page back to the map nor any other page. Punching the soft key buttons at the bottom of the unit did nothing either. Trying to power it off did not work.
In all cases the "left and right + range button reboot trick" worked.
After my earlier post, I went and flew Sunday. I logged 1.8 doing nothing but flying around trying to get it to lock up. The cockpit was probably cooler at start up because the plane was in the hangar but my EFIS said OAT was 32c. As you can probably guess the 696 worked flawlessly.
Have you used yours with cockpit temperatures over 100? There are warnings in the manual not to leave it in a hot airplane in direct sun and it says not to operate it above 140f. I have not done either of those.
We've had so many 100 degree days here this summer that I'd be grounded a lot if it is temperature related. If it happens again, I'll call Garmin regardless of the circumstances. I'll check for software and firmware updates first, though.
