Bought at adaptare. The cable was purchased for the full circuit, to use it as an extension of the charging cable from Garmin. If you firmly mounted the Navi with the foot on the dashboard, which is always at 90 ° angled charging cable on the dashboard. Thus, the sensitive socket is protected on the device, I needed a not angled cable with full wiring. That's what I get, the device detects still charging cable and invites tadelos. The original charger cable with TMC antenna could be relocated so that now everything is tidy. I had indeed passed also 30cm, but since only 1 cable is visible, it still looks tidy from.
So 5 stars for the cable, since it also has full Fuktion.
