I bought a Garmin NüVi 1450… If I connect things with the org car cable everything is OK. However, as planned by me, it switches to PC mode via the USB adapter and adapter cable… So it would have to teach the part that it also concerns. With a 2nd car cable without TCM receiver it also works… That would be the desirable condition for adapter cables (cable mini USB to USB). Suggestions what to change on the cable…?
