Another PS:
I had written another post, but it got lost in the ether because my internet connection broke as I sent it.
The gist of it was, that the bluetooth connection seems to be between the T800 device and the mobile telephone, and perhaps the dashboard. The T800 device itself is apparently connected to the ECU via a conventional OBD adapter, as is Guzzidiag and co.
On the basis of this assumption, I doubt very much that a theoretical version for the V11 models would be able to show things like vehicle speed and gear changes. The more modern models listed in the compatibility lists have dashboards which collect that information, and have a bluetooth capability which is used by the aforementioned MIA application. The V11 models simply don't have bluetooth capabilitly in that regard.
Further to that, I seems that the possibility to download and save the existing map before a new one is installed is not available. That would be a prerequisite for me personally, and if that is not possible, I would stick with the IAW reader and writer programmes.
