Thanks for your input. I've done a considerable amount of research on the CNvXC in the last few days, and arrived at the conclusion that the inability to declare tasks directly from my Oudie is, in fact, the most significant drawback with the vario. However, I think I will only need to upload the task to the secure flight recorder in the CNvXC when I am making the occasional Badge attempt. Otherwise, I will just rely on the waypoints and task in the Oudie for navigation. I never bothered to upload waypoints into my 302. I gather it will be reasonably easy to load waypoints into the CNvXC via the USB stick, so that the basic navigation and glide slope to a point can be done by the device.

I queried ClearNav about the issue of loading/declaring task from a 3rd party device, and was told is that they will, at some point, enable this function. The question, of course, is when?

I also understand that the latest software which is being tested now does, in fact, employ the inertial sensors, and that improved gust filtering can be expected with the next software release. We shall see....

I have gone ahead and pulled the trigger on the new vario -- the timing argued for buying it now, rather than spending more money to repair the 302. It would have been preferable, of course, to wait till the product is "mature" and the software is fully developed, and I sincerely hope ClearNav will push ahead quickly on this.
