Rob,
Could you also add the fix for the timer expiration audio alert which has been previously committed to be fixed (

For what it's worth, I share a bit of Colin's frustration. I think the AFS kit is fantastic. However, when I purchased my 4500s the 5000s had been announced but were not available. I purchased them through Aerotronics and Gary convinced me that it was worth going with the 4500s because 1) you would continue to provide support and upgrades and 2) there would also be an easy upgrade path should I wish to do so at a later date.
I do appreciate that you continue to support and upgrade the 4500s but have a bit of concern that they may be "abandoned" (I believe it has been over a year since an upgrade has been issued). In addition, it remains a bit unclear what, if any upgrade path is available to move to the 5000 series. Dynon has been great in continuing to support the older D180 issuing regular updates and they also provided a great upgrade path to the Skyview for customers like me that were caught in the transition period.
Cheers.
