Desperate for a code for my streetka cd/radio!?

Hi hoping someone can help, have locked my 6000 cd rds e-o-n cd/radio in my streetka 53' plate. Unsure how to remove radio to get the serial number so pressed 6 and 1 together and it came up with this;
50701940
Dp mv sh 
09 - 00 - 00,
Any chance of getting a code with this info?
Many thanks,
Heather
