Otherwise, the processing is good, the design stylish, with especially the white illuminated HTC logo like on the plug. My Desire is charged also using the GPS, WLAN and Mobile interfaces! What more do you want. The coiled cable is possibly not to everyone's taste, I think it's good, it is sufficiently long dimensioned and it flies no unnecessary clutter through the car.
That does not seem the plug mechanically to be compatible with the BMW cars, is strange. So far I never had such a problem! Actually, the 12 V plug should be standardized. With whom the fault lies here at BMW or the accessories manufacturer, is open! Because of the small blemish from me only 4 stars! :-)
