I know OPRAH would yell at me for this, but when my car is in motion I can't put a phone number in the Premium head unit. It only gives me access to the speed dial numbers and nothing else. When I come to a complete stop the keypad re-illuminates and allows me access to dial a number. Am I doing something wrong ? Seems to me it would be safer dialing from the head unit than my cell phone while driving. The manual dosen't say anything about this and i'm wondering if something is wrong with the unit ?
