I'm requesting help in reactivating my car radio. I have an 86 Benz with a Becker Grand Prix, model 754, ser # U6752151. The dealer gave me the code as 34412, but it doesn't seem to work; I still get 4 pairs of dashes when I enter the numbers. After entering the numbers, I've tried about every button, but nothing seems to activate it. Is there a secret method, or could you check the code for me? (It deactivated when the battery depleted with the security system set.) I would appreciate any help available. Thanks.
Louis901 the given code is the right one for that serial. If you have 4 dashes across the display the unit needs to be sent to Becker for repair. Take a look here it should help. http://web.mac.com/dakota/Becker/754.html if its a four digit then it woud be 5412 but i think you find yours is five digit.
