I looked last night at the progress bar, but none was shown. So I thought I leave it running over night. Came down this morning and still no progress shown. So I took the disk out but when going on MAP the satnav said to insert a navigation DVD, so I put it back in. When pressing EJECT it showed the screen saying that the maps are being downloaded and if I eject the disk the process will be aborted, but the progress bar did not move (even not after 1/2 hour). So I took it out again and now the SETUP menu shows now no maps installed. So I used my old V3 disk again to reinstall the old maps and this is showing progress and it is about 3/4 through the installation. After the old map is back on, I will try the update disk again, I think.
