Yeah I think that's the case (reads data but nothing else). I can't update my software using OTA or usb anyway I've found - I'm in Oz and seems you have to get non-US version files. And a uConnect 5 upgrade is silly money even if you source the parts yourself here.I lost my off-road/performance pages when I upgraded to the pr-40 app version. They are still showing as enabled in alfaObd, but don't show up. Most of the stuff didn't work anyways, so not really missing them.
