"Can't imagine what you are doing that "requires large amounts of button pressing and concentration" in flight on CN2. Most users have a very different experience."

I can only go from my experiences, e.g. changing from total distance to run and glide to distance to the next TP takes a lot of poking around. On the LX it is no effort at all as you can display both at the same time, should you wish. My general impression was that it took more effort on the part of the pilot to perform similar actions using the CN2 compared with the LX and over a long flight that adds up. I used the CN/LX back-to-back in the same task area.

The OLC "feature" froze the display for 20-30s when accessed which didn't help the first time as I was close to airspace. Attempting to add a new TP on the grid as it wasn't in the database made the unit crash completely, needing the power removed.

I appreciate there might have been some revisions since I last tried it but this was less than a year ago with the (then) latest firmware. I really wanted to like it but it I was surprised how "beta" it behaved. I'm flying a glider in a couple of weeks with a CN2, so will give it another go...
