I have a Becker Grand Prix (Model 754, Serial# - U6781894) in my 1987 300E. The radio won't turn on for some reason since a few weeks ago. I am still troubleshooting the cause, but at the mean time I had dismounted the radio to check the fuse, after disconnecting the power. I would really appreciate help on obtaining the code. I purchased the car from Smyth European in San Jose back in 1987. The VID is WDBEA30D4HA333460.

Thanks in advance.
