Jay,As you have said the first update of Medianav is a two-stage process, well it was for me. I think that once you have done the first update, as you appear to have done, you will need to go through that self-same process again. That is reformat your memory stick your home computer. Take the "empty" newly formatted memory stick to the car, and do the "update" process again. This will load the latest information from your car's MediaNav system onto the memory stick. Then take that memory stick back to your home computer and then the MediaNav toolbox will recognise the memory stick contents and download the next set of data, which you then take back to the car and update in just the same way as your did the first time.
You will have then completed the two-stage update. I think from then on in, the update will be a single stage process. But in order to do that you will have to reformat the memory stick, load the MediaNav details from the car, use the toolbox download the latest update, and take it back to the car.
I suspect that the download process from the toolbox onto the memory stick puts files onto it that are needed for the update, but does not carry the information in the form needed by the toolbox to recognise for subsequent updates. This is why you have to reformat the memory stick and take the blank memory stick to the car to load the MediaNav information onto it so that the toolbox can recognise the version of the update needed.
