Hello everyone,
Got a problem with HK7. Everything works: FM, CD, DVD, AUX, NAV, but when you go to the setting of Logic7 and switching on/off there ain't any difference in sound, feels like you would play over the phone. Bought a new amplifier, but it did not help. The diagnostic came up that the VIN number is not correct on the old amplifier, the same with the new one. Maybe some one can help?
