I understand where Bob is coming from, i.e. recommending that we avoid potentially damaging mods to our kit.
As such, I'm going with his recommendation and have just called my dealer regarding the plan for firmware updates to my 568.2.
Their reply was that they will talk to Meridian on Mon and get back to me. I do hope that this suggestion of a firmware update is not simply vapourware, as I'll not be impressed. The kit might be built to "last a lifetime", Personally I'd prefer not to have to wait that long.

On a positive note, and just so Meridian know, if there were to be a dealer firmware update, assuming the it was a sensible price, e.g. sub �100, then I'd pay for it if it was appropriately tested and warrantied.
