Moin, on the other hand, let me download the corresponding IAM-up-date from Volvo to download the current Sensus Navi software. On Stick- 64 GB- the current update, 21 GB, is downloaded. When playing up in the vehicle, however, zero happens. The stick initially flashes when switching on the Navi- that was then also. no reaction of the Navi to the stick. However, software is on the stick- I have formatted with NTSC and exFat. Any idea?
